Does the Bible say to follow your heart?

Yes, it was good and right to trust in Jehovah with all the heart, and to lean not on one's own discernment, as the tempter always advises to ruin, sorrow, and shame. This is the divine counsel for the heart. But the Israelite needed also to "acknowledge Him" in all his ways. And the heart if loyal would prompt to honour Him thus. For practical inconsistency is a burden to the upright; and it is due to Jehovah to own Him where He is apt to be ignored or forgotten in each detail of walk, and in them all. Nor was it even without present fruit, for He could not be unmindful, who never slumbers or sleeps. "And He shall make straight thy paths." He is Lord of all, no less than He is the Eternal, and concerns Himself with every obstacle and difficulty for such as would walk unswervingly according to His will.

Verses 5 and 6 were deeply impressed on the writer at an early age, and have no doubt spoken seriously to many others before and since that time. There are many things in which our understanding is extremely faulty, and if we depend on it, we shall be badly misled. the only safe alternative is to trust in the Lord with all our heart. that is, fully and without reserve. He will certainly not deceive us, nor is there any possibility of His making a mistake.

Cursed is man that trusts in man, says the prophet (Jer. 17:5), and he that trusts his own heart is a fool (Prov. 28:26). “Trust in the Lord with all thine heart, and lean not unto thine own understanding” (Prov. 3:5) God has set man in dependence upon Himself, and therefore no one needs think himself quite competent to take up eternal problems, and to solve them by his own natural intelligence; for should he make any such attempt he is as certain to go astray as though to go astray was the one desire of his heart.

It is a fact beyond dispute that each of us is acquainted with a man that we are sorely tempted to trust. We are more likely to trust in him than in all other men put together. The man you are likely to trust is yourself. The man I am likely to trust is myself. Yet, “He that trusts in his own heart is a fool” (Prov. 28:26).

With our will unbroken, we are unable to discern and to prove what is that good, and acceptable, and perfect will of God, whether as to the practical difficulties of daily life, or as to His work and service. As the fog conceals the sun, so our own will hides from us the will of God. But if in the school of deep trials and sorrows, often alas! caused by our self-will, we have learnt to judge our evil, foolish, and perverse will, and to abhor it, we shall be able "to prove what is that good and acceptable and perfect will of God." As with the will, so with the heart. "He that trusteth in his own heart is a fool." And why? Because it "is desperately wicked," and "deceitful above all things." None but a fool would trust a wicked man, or believe one who is a thorough deceiver. In your heart do you confide? God's heart from yourself you hide.

He now enters into details in verses 5 and following. Two paths are before man - to trust God, or himself and his own wisdom for his happiness. This is just what Eve failed in; she did not confide in God, trust in Him and what He had said, for her happiness, but leaned to her own understanding, thought she should better secure it by doing what she thought would be advantageous. So every sinner; he thinks he can better secure his own happiness in doing his own will than in listening to God. Trust in God is the first positive active principle of life and wisdom; the next is owning Him in our ways, taking His will, authority, as that which is to form them, not our will and wisdom, and that openly (v. 6). He will surely direct our steps. No human wisdom can guide like that. It may be very cunning - know human nature. But God has a way which He has laid down morally for us - a path of obedience, of righteousness, and of God; and He who has done so orders all things. In the end His judgment will prevail. We may not see it prevail here - thus faith may be exercised; where His direct government is exercised, it will, but always in result. The end of the Lord is sure; heaviness may endure for a night, for a season if need be; but, for the faithful soul, joy comes in the morning, a morning near to come. But self-confidence is ruin. "Be not wise in thine own eyes" (v. 7). They do not see far if they only see self, and that is what always is in our own eyes. The fear of God, as we have seen, the moral path of His fear, is that on which He waits in goodness, however things may seem - this, and departing from all evil. This is something more than walking in His fear - there is an abhorrence of evil, partly in itself, partly as contrary to His will. I may walk in God's fear, do no evil myself, without, I think, being characterised by departing from evil. No doubt, walking rightly is not doing evil. But evil is in the world, and there is, so to speak, a positive character of relationship to it, that is, departing from it, abhorrence of it. Adam, innocent, would have walked uprightly, done nothing wrong; he would not have departed from evil, he had nothing to say to it. I have or may have. I depart from it, leave and break with it. This has to do with holiness. We have seen Jehovah owned by confidence, and in His servant's ways. It requires confidence in Him to guide one's ways by His will. Now we come to another way of owning devotedness of heart, owning all positive good and blessing to come from Him, and manifested in the ready but due offering of a willing heart. Thus blessing is found, temporal blessing; v. 8-10. It must be remembered that we are always here on the ground of present government in the earth. Higher objects may bring sorrow as regards this world, as it has ever been. Now we can only apply the principle. Peter's epistles give the degree in which this government applies to Christian standing.

But now there is another matter, and it is this. We spoke of the young man starting on the voyage of life, his hand apparently holding the tiller, and guiding the ship. Now many a young man, and even a young believer, thinks that this is not only apparently, but is really so, and that he is the architect of his own fortunes, and that it is his will that is to direct his future life. Many accept Christ as their Saviour, who have but a very faint idea of what it is to accept God as their Father; and yet the one relationship is as true as the other. And if the one makes them happy for eternity , the other is certainly the secret of true happiness for time . There is a wonderful difference between the young man who goes forth rejoicing in his own strength and sagacity, and thinks that he can outwit the world, and the humble Christian who leaves home placing the tiller of the little vessel of his life into his Father's hand, and trusts Him to guide him aright through the dangers and difficulties of each day. “Trust in the Lord with all thine heart; and lean not unto thine own understanding.” Do not think that any detail of your new life is too small for God to guide you in. The choice of your business, of your future home, of your companions, should all be entrusted to Him; and He will greatly own and honor such confidence, and lead you in the very best path . For it is folly to suppose that if we have a loving and all-wise Father, He would or could do anything else. The poet's words are indeed true:

316 There may be direct guidance, I cannot call it into question: when it is given, it is not fanaticism. We get right impressions by living with Christ. John did not go and get a place near Christ in order to know His secrets; but he had a place near Christ, and then the secrets were given to him. Only you cannot go properly to Christ, as John, to ask, unless you are living near Him. Only "trust in the Lord with all thine heart, and lean not to thine own understanding." You must live near the Lord, or you cannot reckon rightly on being guided. God's mercy may come in at any time, but "the secret of the Lord is with them that fear him." I should be filled with the knowledge of His will, and all spiritual understanding.

Yet we are told to “cease from thine own wisdom,” which means that wisdom cannot be rightly used save as you “trust in the Lord with all thine heart”—wisdom must not be divorced from real communion with and dependence upon the Lord.

Dear reader, “Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge Him, and He shall direct thy paths. Be not wise in thine own eyes: fear the Lord, and depart from evil” (Prov. 3:7).
