Barnes’ Notes on the Bible
The answer to the question, “who can know it?” To himself a man’s heart is an inscrutable mystery: God alone can fathom it.
Ways – Rather, way, his course of life. The “and” must be omitted, for the last clause explains what is meant “by man’s way,” when he comes before God for judgment. It is “the fruit,” the final result “of his doings, i. e., his real character as formed by the acts and habits of his life.
Gill’s Exposition of the Entire Bible
I the Lord search the heart,…. The inward parts of it, every room and corner in it; and know the thoughts of it; all its intents, purposes, designs, contrivances, and imaginations; all the secret motions of it, and the wickedness that is in it; so that this is an answer to the question in the preceding verse; and therefore, though the heart is deceitful, it cannot deceive him, because he judges not according to outward appearance; he sees and knows the heart; and none but the Lord, or he who is Jehovah, can so search the heart as thus to know it; wherefore, since Christ is said to search the reins and the heart, and to know the thoughts of men, and to be a discerner of the thoughts and intents of the heart, he must be Jehovah, and the true God, Revelation 2:23,
I try the reins; the most inward and remote parts, covered with fat, and out of sight: these are the seat of the affections; and the Lord tries these, whether they are towards him or not; and whether sincere or hypocritical;
Christ the omniscient God knew Peter’s love to him, and the sincerity of it; for which he appeals to him as such, John 21:17, even to give every man accordions to his ways, and according to the fruit of his doings; to do which it is necessary to search the heart, and try the reins, the fountain of all actions; and in which the principles of them are, and according to which they are denominated and judged of: in the future judgment every secret thing will be brought into account; the counsels of the heart will be made manifest; the book of conscience will be opened; and out of it, as well as other books, men will be judged according to their ways and works; and therefore it is requisite that the Judge should be the Lord God omniscient, the searcher and trier of the hearts and reins, as Christ is.
