What does the Bible say about strength?
Answered from the commentary of Hamilton Smith, An Outline of Sound Words, H. J. Vine and 18 others
Scripture teaches that the believer has no strength of his own and that all his real strength is in the Lord. Natural strength, even at its freshest, fails: "even the youths shall faint and be weary" (Isaiah 40:30), and it is a hard lesson that the strength of nature cannot keep anyone in the path of faith. God, who never faints, "giveth power to the faint," and it is those who wait on the Lord, looking to Him alone and expecting from Him only, who renew or change their strength (Isaiah 40:29-31). This renewal is spiritual rather than physical. It carries the believer through youth, middle age and old age, even to the end. The same truth comes in the New Testament through Christ: "without Me ye can do nothing" (John 15:5), yet "I can do all things through Christ which strengtheneth me" (Philippians 4:13). This was a real experience for Paul of Christ's sufficiency in every circumstance, and not an abstract claim. Because of this, the Lord never gives His people a strength of their own; He makes them feel their dependence. Paul's thorn was not removed, and he learned instead that "My strength is made perfect in weakness," so that he could say, "when I am weak, then am I strong" (2 Corinthians 12:9-10). The thorn guarded him against pride and made way for the power of Christ to rest on him.
From this come the exhortations. "Be strong in the Lord, and in the power of His might" (Ephesians 6:10) means being strengthened by coming constantly to Him, and it stands against foes for whom the believer is no match on his own. That strength is drawn on only in communion with Christ, which Satan labours to break. Paul also prays that believers be "strengthened with might by His Spirit in the inner man" (Ephesians 3:16), because the new nature depends on the Holy Spirit for power, so that Christ may dwell in the heart. "The joy of the Lord is your strength" (Nehemiah 8:10) is joy in the Lord and not in circumstances. Such joy overflows in blessing to others, and a joyless Christian is a weak one. The promise "as thy days, so shall thy strength be" (Deuteronomy 33:25) holds for the one who walks in the power of the Spirit. For the same reason, trusting in chariots, horses or any human resource is vain, since deliverance is of the Lord alone (Psalm 20:7). The call to "be strong and of a good courage" rests on God's command and on His presence (Joshua 1:9). Such courage is founded on Christ, whereas presumption is courage founded on self. That presence is known in the path of His will and of holiness. Samson is the solemn warning: his strength hung on his separation to God, and when that was given up the strength went, and "he wist not that the Lord was departed from him" (Judges 16:20). The law's demand to love God "with all thy strength" (Deuteronomy 6:5) was given to man "without strength," and only Christ fulfilled it. Finally, whatever strength grace gives is for others, for "we that are strong ought to bear the infirmities of the weak, and not to please ourselves" (Romans 15:1), after the pattern of Christ, who pleased not Himself.

What the commentators say
The passages the answer is drawn from, the most direct first, with the words that bear on the question marked.
(V. 10). The Apostle first directs our thoughts to the power that is for us before he describes the power that is against us. To face this conflict we must ever remember that all our strength is in the Lord. Paul therefore says, “Be strong in the Lord, and in the power of His might.” Our difficulty oftentimes is to realise that we have no strength in ourselves. Naturally we should like to be strong in numbers, strong in gifts, or strong in the power of some forceful leader, but our real and only strength is “in the Lord, and in the power of His might”.
The prayer of the first chapter brings before us the power of God's might. Christ has been raised from the dead and set at God's right hand in heavenly places, “far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come”. Now, says the Apostle, that is the “exceeding greatness of His power to us-ward who believe”. The power that is against us is far greater than our power, but the power that is toward us is a surpassing power — it surpasses all the power that is opposed to us. Moreover, the One that has supreme power is the One that possesses “unsearchable riches”, and loves us with a love that “passes knowledge” (Ephesians 3:8, 19).
Reckon yourselves to be dead, because Christ has died. When you go down to this world, the only possible dealing with the flesh is making nothing of you. This is not power, but it is the way God deals with us to give power, whether to an apostle or to the giver of a cup of cold water. If you are in Christ, one wants nothing but Christ from you. The thorn is not power in itself, but preparation for power. Suppose Paul despicable in his ministry: well, there never was such a work done before. Then there must be something besides Paul here; Christ must be here. Ah! says Paul, "I glory in my infirmities that the power of Christ may rest upon me." His strength is made perfect in weakness. He cannot make it perfect in our strength! I am as weak as water — a poor weak thing: God has chosen that no flesh may glory in His presence. Where a person is nothing, "my grace is sufficient." Where is His strength made perfect? In a person who has no strength at all: then it must be Christ. When I am made nothing of, "I glory in my infirmities." There is what the Christian is.
"I-have-strength-for all-(things) in the-(One) empowering me." (Phil. 4:13). What wonderful words to come from a man in prison, one who was apparently in most abject circumstances, and in no small danger: one who was unable to do anything, as men would say. But faith speaks according to God, and the one who could do nothing, in the judgment of others, is the very one who could say he had strength for all things: — not in himself, truly, but, — in the One empowering him. The word translated 'empowering' is the word from which we get dynamite and dynamo; what mighty power is expressed in each of those words: but the One who empowered Paul was mightier than all dynamite and all dynamos. He is the One who could say: "All power is given unto Me in heaven and on earth." And therefore we are to go into all the world and preach the Gospel. And it is because all power is given unto Christ that we may take up Paul's language (for we have the very same One to empower us) and say: "I have strength for all things in the One empowering me." Our Lord Jesus said truly: "Without Me ye can do nothing." (John 15:5). But here we have the other side: "In the One empowering" us, we can do all things.
1916 27 It is well when Christians in conscious weakness (for indeed, we are as water spilt upon the ground which cannot be gathered up again) "wait upon the Lord," for "in the Lord Jehovah is everlasting strength;" and we are told "he that waiteth upon his Master shall be honoured." At the time Isaiah spoke, all was weakness and confusion in Israel; but although their condition was so sad in the Lord's sight, yet in the riches of God's grace the prophet was given to utter by the Holy Spirit these memorable and reassuring words, "Hast thou not known? hast thou not heard, that the everlasting God, Jehovah, the Creator of the ends of the earth, fainteth not, neither is weary? There is no searching of his understanding. He giveth power to the faint; and to them that have no might he increaseth strength." Thus He recalled them to the inexhaustible source of strength to be found alone in Himself. Their youths and young men, in whom strength and vitality would naturally be looked for, had utterly failed, and everything was in a state of complete prostration. Then came the blessed and definite promise (surely not less for us than for Israel) "they that wait upon Jehovah shall renew, or change their strength. They shall mount up as with the wings of eagles, they shall run and not be weary, they shall walk and not faint." Faintness and weariness are thus overcome, and power given to run in His service, and strength imparted to walk circumspectly, not as fools, but as wise, to all those who wait upon the Lord.
In Nehemiah 8 two things come out — a deepening love for, and intelligence in, the Word of God. "The Levites caused the people to understand the law: and the people stood in their place. So they read in the book in the law of God distinctly, and gave the sense, and caused them to understand the reading." … And all the people wept when they heard the words of the law (Neh. 8:7-9). Ah! the word had great power that day on the hearts and consciences of the people. And what followed this real heart-searching? Blessing, of course. "Nehemiah and Ezra the priest the scribe, and the Levites that taught the people, said, Mourn not, nor weep, neither be ye sorry; for the joy of the Lord is your strength." And at verse 12 we read of great mirth, "because they had understood the words that were declared to them." They wept, for they knew how weak they were; but joy filled their hearts because God was their strength. It is well to feel our weakness, and to acknowledge it; but what cause for joy when we learn the strength of the Lord is ours! The joy of the Lord must be that which sustains us. Then we have strength outside, and in spite, of all circumstances. Individually we ought to be so happy and so sure of our position that we have a portion to give to others. Streams of blessing should flow from us; we should be a refreshment to every one who crosses our path.
13 Let us turn to the third part of the subject - that obedience is the order of special gift. We have here direct and topical instruction of Scripture on the subject, in chapter 15 of John's gospel. Of the principle of it we have an illustrious instance in Samson and his history. There was one separated to God, sanctified for Jehovah, and therefore put into the order of defined obedience; his hair was not to be cut. While the commandment and precept were observed, his strength was with him. There might have seemed little connection between long or uncut hair, and all-overcoming strength; but God was in it: and an obeyed, honoured, God is a God of strength to us. It was God's strength, and given to one so definitely recognising Him; it was a gift hanging (as to its retention) on obedience - consistency with the undertaken vow of separatedness to God. The surrender of this secret betrayed to the world the corrupting influence which had wound round the deceived Nazarite. His locks were cut by one nominally the friend and associate of the God-devoted man, in truth the sure ally of the Philistines, and suited instrument of Satan's power. Once shorn of his strength, and in the Philistines' hands, his eyes are put out; and, if in any sort he regains his strength, it is blindly to destroy himself with his enemies. That which I insist on here, however, is the sign of separation to obedience being the order and hinge of the possession of the given strength, the presence or absence of the one depending upon the presence or absence of the other, however unconscious the unhappy victim was of the strength of others thereupon against him: a sorrowful yet instructive history to our weak and wayward will.
“We then that are strong ought to bear the infirmities of the weak, and not to please ourselves.” Does one Christian have the privilege of clear enlightenment whereby spiritual strength is given him? If so, he “ought to bear the infirmities of the weak.” It is a moral responsibility (he “ought to”), that he might properly represent “the God of patience and consolation.” For our God has seen fit in infinite grace that His glory should be intimately connected with the welfare and blessing of all His people. Blessed truth to contemplate! With such thoughts before us, can we dare to callously proceed to please only ourselves? If we are blessed, it is not in order that we might proudly display ourselves, but in order that we might be a blessing to others.
Just as a mighty man has confidence in his own strength, which in the long run fails him, so he may also trust the strength of a war horse, but this is a vain hope, for eventually he will find even the great strength of the horse to fail him. So people choose many methods of self-defense which only prove to be useless in preserving them, because they are not depending on their Creator. But we all seem to be very slow in learning this most elementary lesson, that the strength of the creature in any form is pathetically weak and we require the strength of God to preserve us.
293 Before we come to power, the question of righteousness has been settled by Christ being at the right hand of God; it is a settled thing. It is practically learned when I am saved; then I have a title to the third heaven; and strength is made perfect in weakness. The Lord never gives us intrinsic strength, He makes us feel our dependence. I am made to feel my weakness when I see how my flesh would even pervert the blessings that are mine in Christ. Therefore will I rather glory in infirmities (not sin, but infirmities - for example, distresses, persecutions, etc.). The Spirit kept him from that which would have given him a bad conscience.
And what is the exhortation He sends? It is, "Be strong;" and the source of their strength is the knowledge of the fact that He is with them. It is so everywhere in the Scriptures. Take two examples: "Fear not, Abram: I am thy shield, thy exceeding great reward." (Genesis 15:1.) Again, "Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the Lord thy God is with thee whithersoever thou goest" (Joshua 1:9.) It was on this account, when the Lord commissioned the twelve to go and teach all nations, etc., that He added, "And, lo, I am with you alway, even unto the end of the age." (Matt. 28) It is indeed impossible but that the assurance of the Lord's presence should inspire His people with fortitude and courage. If He is with us, resting confidently in what He is for us, we measure our foes and difficulties, not by what we are, or by our own resources, but by what He is in all His own omnipotence. Then we can boldly say with one of old, "They that are with us be more than they that be with them;" or with the apostle, "If God be for us, who can be against us?" It was in this way the Lord would strengthen His poor feeble people in all the poverty of their circumstances; He would attract their eyes to Himself, that they might labour in faith, fearing no foe because their God, who was with them, had thrown around them His impenetrable shield. He reminds them, moreover, of His faithfulness to His covenant which He made with them, when He redeemed them out of Egypt, according to which His Spirit remained among them. (See Isaiah 18:11-14.) Hence He adds, "Fear ye not." Jehovah Himself in their midst, and His Spirit remaining among them, they might well take up the language of the Psalmist: "The Lord is my light and my salvation; whom shall I fear? the Lord is the strength of my life; of whom shall I be afraid?"
