Heart

According to the Bible, the heart is the centre not only of spiritual activity, but of all the operations of human life. "Heart" and "soul" are often used interchangeably (Deut. 6:5; 26:16; comp. Matt. 22:37; Mark 12:30, 33), but this is not generally the case. The heart is the "home of the personal life," and hence a man is designated, according to his heart, wise (1 Kings 3:12, etc.), pure (Ps. 24:4; Matt. 5:8, etc.), upright and righteous (Gen. 20:5, 6; Ps. 11:2; 78:72), pious and good (Luke 8:15), etc. In these and such passages the word "soul" could not be substituted for "heart." The heart is also the seat of the conscience (Rom. 2:15). It is naturally wicked (Gen. 8:21), and hence it contaminates the whole life and character (Matt. 12:34; 15:18; comp. Eccl. 8:11; Ps. 73:7). Hence the heart must be changed, regenerated (Ezek. 36:26; 11:19; Ps. 51:10-14), before a man can willingly obey God. The process of salvation begins in the heart by the believing reception of the testimony of God, while the rejection of that testimony hardens the heart (Ps. 95:8; Prov. 28:14; 2 Chr. 36:13). "Hardness of heart evidences itself by light views of sin; partial acknowledgment and confession of it; pride and conceit; ingratitude; unconcern about the word and ordinances of God; inattention to divine providences; stifling convictions of conscience; shunning reproof; presumption, and general ignorance of divine things."

The Hebrews regarded the heart as the source of wit, understanding, love, courage, grief, and pleasure. Hence are derived many modes of expression. “An honest and good heart,” Luke viii, 15, is a heart studious of holiness, being prepared by the Spirit of God to receive the word with due affections, dispositions, and resolutions. We read of a broken heart, a clean heart, an evil heart, a liberal heart. To “turn the heart of the fathers to the children, and the heart of the children to their fathers,” Mal. iv, 6, signifies to cause them to be perfectly reconciled, and that they should be of the same mind. To want heart, sometimes denotes to want understanding and prudence: “Ephraim is like a silly dove, without heart,” Hosea vii, 11. “O fools, and slow of heart,” Luke xxiv, 25; that is, ignorant, and without understanding. “This people’s heart is waxed gross, lest they should understand with their heart,” Matt. xiii, 15; their heart is become incapable of understanding spiritual things; they resist the light, and are proof against all impressions of truth. “The prophets prophesy out of their own heart,” Ezekiel xiii, 2; that is, according to their own imagination, without any warrant from God. The heart is said to be dilated by joy, contracted by sadness, broken by sorrow, to grow fat, and be hardened by prosperity. The heart melts under discouragement, forsakes one under terror, is desolate in affliction, and fluctuating in doubt. To speak to any one’s heart is to comfort him, to say pleasing and affecting things to him. The heart expresses also the middle part of any thing: “Tyre is in the heart of the seas,” Ezekiel xxvii, 4; in the midst of the seas. “We will not fear though the mountains be carried into the heart (middle) of the sea,” Psalm xlvi, 2. The heart of man is naturally depraved and inclined to evil, Jer. xvii, 9. A divine power is requisite for its renovation, John iii, 1–11. When thus renewed, the effects will be seen in the temper, conversation, and conduct at large. Hardness of heart is that state in which a sinner is inclined to, and actually goes on in, rebellion against God.
