Why do so many people struggle with a lack of faith?

Answered from the commentary of C. H. Mackintosh, J. Wilson Smith, Andrew Miller and 4 others

So many people struggle with a lack of faith because unbelief is natural to the human heart, which is slow to trust God’s word and often prefers its own judgment, will and feelings. Instead of resting on God’s testimony and Christ’s finished work, people look for visible signs, turn inward to inspect their faith, or wait for feelings that will reassure them. Even believers can be occupied with themselves and their changing experience rather than Christ, and so remain in doubt and uncertainty.

Difficulties, anxiety and worldly concerns can also draw the heart away from trust: trials may perplex us, while the cares of life, riches and other desires crowd out the word. Some lack settled peace because they have not understood the full results of Christ’s work; others know little of Christ’s person, or have not rested simply on what God has said. The authors differ on which cause is at work in each person, saying that the reasons vary, but they commonly trace the struggle to distrust of God and failure to give His word its proper authority.

The passages the answer is drawn from, the most direct first, with the words that bear on the question marked.

C. H. MackintoshChrist in the Vessel

But alas, we are unbelieving! Here lies the source of weakness and failure. We are perplexed and agitated, when we ought to be calm and confiding; we are casting about, when we ought to be counting on God; we are "beckoning to our partners," when we ought to be looking to Jesus. Thus it is we lose immensely, and dishonour the Lord in our ways. Doubtless there are few things for which we have to be more deeply humbled than our tendency to distrust the Lord when difficulties and trials present themselves; and assuredly we grieve the heart of Jesus by thus distrusting Him, for distrust must always wound a loving heart. Look, for example, at the scene between Joseph and his brethren in Genesis 50.

C. H. MackintoshChrist in the Vessel

Such was Jesus — very God and very man — and such He is now, ever ready to meet His people's need, to hush their anxieties and remove their fears. Oh that we trusted Him more simply! We have little idea of how much we lose by not leaning more on the arm of Jesus, day by day. We are so easily terrified. Every breath of wind, every wave, every cloud, agitates and depresses us. Instead of calmly lying down and reposing beside our Lord, we are full of terror and perplexity. Instead of using the storm as an occasion for trusting Him, we make it an occasion for doubting Him. No sooner does some trifling trouble arise than we think we are going to perish, although He assures us that He has numbered the very hairs of our head. Well may He say to us as He said to His disciples, "Why are ye so fearful? How is it that ye have no faith?"

C. H. MackintoshSection 3 of 10

This is the divine basis of peace. The more simply we build thereon, the more solid our peace will be. The reason why so many are in a state of miserable uncertainty is because they do not rest in absolute faith on God's foundation. They are occupied with themselves instead of building exclusively on Christ. They are looking to experience rather than to a risen Savior. Feelings and attainments engage them instead of Christ. They are vainly hoping to find some sort of improvement in themselves, and not finding it to their satisfaction — for what honest soul ever does? — they are filled with gloomy doubts. The heart is oppressed with anxious fear and the spirit is overcast with heavy clouds. They have no divine certainty, so they try to find comfort in the exercises of a religious life. Inasmuch as imperfection attaches to their very best and most pious exercises, they are ever kept in a condition of spiritual darkness and bondage. Neither in our inward feelings and experiences, nor in our outward exercises — of whatsoever kind these may be — have we the true ground of our peace in the divine presence. God did not send to the children of Israel, nor does He now send to us Gentiles, peace by spiritual experiences or by religious exercises, but simply by Jesus Christ.

C. H. MackintoshExodus 1 - 14, Section 1 of 2

It is because these foundation-truths are not laid hold of in the simplicity of faith that many of the children of God complain of their lack of settled peace — the constant variation in their spiritual condition — the continual ups and downs in their experience. Every doubt in the heart of a Christian is a dishonour done to the word of God and the sacrifice of Christ. It is because he does not, even now, bask in the light which shall shine from the judgement-seat, that he is ever afflicted with a doubt or a fear. And yet those things which so many have to deplore — those fluctuation's and waverings are but trifling consequences, comparatively, inasmuch as they merely affect their experience. The effect produced upon their worship, their service, and their testimony, is far more serious, inasmuch as the Lord's honour is concerned. But, alas! this latter is but little thought of, generally speaking, simply because personal salvation is the grand object — the aim and end, with the majority of professing Christians. We are prone to look upon everything that affects ourselves as essential; whereas, all that merely affects the glory of Christ in and by us is counted non-essential.

VariousNotes and Reflections on the Epistle to the Romans

It is instructive to remark, that the communings of a man's heart with itself ever result in an expression of unbelief. A sign is desired (verses 6, 7), where God is not already in possession of the heart's confidence through faith. And is it not often thus in the case of those who now are seeking peace, yet find it not? Haply, some reader of these Notes may find his own heart painfully familiar with those care-trodden ways in which the tired spirit vainly seeks to find that peace which God may seem to have hidden from the fainting desires of the soul. If such an one has found the name of Christ as yet insufficient to dispel his fears, and to pour the full joy of salvation into his bosom, let him be assured that the cause of his distress is not only within his view, if he will turn his eyes towards it by the light of this precious word of faithful witness, but also that it is within the power of his own removal, if he be only willing to put more honour upon the eternal truth of the living God, than upon the mutable counsels and most fallacious suggestions of his own weak and joyless heart.

Other AuthorsH. P. Barker

Multitudes lack settled peace because they are unbelieving believers. When the Lord Jesus joined the two wanderers on the road to Emmaus, He found them, true disciples though they were, full of unbelief. "O fools," He said to them, "and slow of heart to believe all that the prophets have spoken."

A. J. PollockWhere Does the Security of the Believer Lie?

So many a trembling believer is troubled by doubts and fears, but if be realised that his security lies in Christ, and in what He has done, and not in himself, his doubts would vanish. We cannot doubt Christ nor the sufficiency of His work.

The Christian's FriendGod's Salvation

Let us remember that doubts and fears, and a joy often followed by darkness and despair, form no part of God's provision for the poor sinner who comes to Christ. Long enough indeed has he known these, and deeply enough has he proved them, in the long and weary years of unbelief that have passed. Yet in how many cases do we find, alas, that these things are perpetuated, even looked upon as right, and too often encouraged as a proof of humility in the children of God! Some sad misunderstanding of the word "salvation," then, must surely exist in our own day, to produce such fruits, and such Christians, and such teachers, as these. The fault is not in God, nor in the Word - this cannot be; it is alone in ourselves. We have to learn, and often through deep sorrow, what we refuse to accept from God by faith. The exercises of Romans 7 teach us this. The soul there is wholly occupied with self as alive.

Andrew MillerThe Grace and Glory of God

WE have frequently had submitted to us, in substance, the following question and remarks, namely, "Why is it that so many sincere Christians never get rid of doubts, fears, and questionings, as to the full assurance of their salvation? Sometimes they seem sure, and are bright and happy, but in a little while they seem depressed, doubt their interest in Christ, and are most unhappy. We know of some who are every now and then on the borders of despair, and even when they do find something like peace, they are in constant terror that it will not last long; so that it can never be said of such that they have true peace or rest."

W. T. P. WolstonGospel Narratives

All this is like some doubting, fearing, unhappy Christians, who tell me they believe on the Lord, and yet they have not peace. They are full of fears; they are not sure He has received them and forgiven them: they do not know His heart; and another thing, they have never had all out with Him. Have no reserves, my reader. Have it all out with Jesus, and do not you be the one to make our Joseph weep; for the heart of the Lord Jesus feels today your lack of trust in Him, after all He has done for you, all the kindness and the love He has shown to you. Wound not then His loving heart by any lack of confidence in Him.

And Peter, having descended from the ship, walked upon the waters to go to Jesus. 30But seeing the wind strong he was afraid; and beginning to sink he cried out, saying, Lord, save me. 31And immediately Jesus stretched out his hand and caught hold of him, and says to him, O thou of little faith, why didst thou doubt?
  • Matthew 17:19–2019Then the disciples, coming to Jesus apart, said [to him], Why were not we able to cast him out? 20And he says to them, Because of your unbelief; for verily I say unto you, If ye have faith as a grain of mustard [seed], ye shall say to this mountain, Be transported hence there, and it shall transport itself; and nothing shall be impossible to you.
  • Mark 4:35–4035And on that day, when evening was come, he says to them, Let us go over to the other side 36and having sent away the crowd, they take him with [them], as he was, in the ship. But other ships also were with him. 37And there comes a violent gust of wind, and the waves beat into the ship, so that it already filled. 38And he was in the stern sleeping on the cushion. And they awake him up and say to him, Teacher, dost thou not care that we are perishing? 39And awaking up he rebuked the wind, and said to the sea, Silence; be mute. And the wind fell, and there was a great calm. 40And he said to them, Why are ye [thus] fearful? how [is it] ye have not faith?
