2. Among other ways of impressing it on our minds, the two parables of the Lost Sheep and of the Prodigal Son (Luke, chap. 15), are exceedingly affecting, and are so abundant in divine consolation, that it is scarcely possible seriously to think upon them without tears. Therein our Saviour describes three different hearts. Of these the first is, the impenitent heart of a sinner; the second, the contrite heart of a penitent; the third, the heart of God, full of mercy and paternal affection.
3. The first he describes under the similitude of a degenerate son, wastefully spending his substance and inheritance, and at last reduced to such necessity, as to wish to fill his belly with the husks which the swine did eat. By this figure all mankind in their natural state are shadowed forth; who, as so many degenerate sons, have squandered away the heavenly inheritance by continual riot and wickedness. That is, they have lost their original righteousness, holiness, innocency, and the beautiful image of God, in which they were at first created (Eph. 4:24), and are now by their own fault become the bond-slaves of sin, of the devil, and of death. And to complete their ruin, finding no relief, rest, or comfort, in any human performances and laws (which answer to the husks in the parable) they must of necessity perish with endless famine and misery, unless they speedily have recourse unto the grace of their Heavenly Father.
4. The second heart, which is that of a repenting sinner, is set forth in these words: “How many hired servants of my Father have bread enough, and to spare, and I perish with hunger! I will arise, and go to my Father, and will say unto him, Father, I have sinned against heaven, and before thee; and am no more worthy to be called thy son.” In this account we have a very moving description of true repentance. By the Prodigal's coming to himself, is signified sorrow for sin; that is, when a man, on the one hand, reflects upon his own misery, and considers how, from being a child of God, he is become, as it were, a brute beast (2 Pet. 2:12), an unclean swine, a man void of reason, earthly and sensual; and, on the other, mindful of his divine origin, turns his thoughts entirely upon his Father, repents, acknowledges his offences, and says, “Father, I have sinned against heaven, and before thee;” and have offended both God and man. [pg 189] This he immediately confirms by a sincere contempt of himself, expressed in these words: “and am no more worthy to be called thy son.” Moreover, faith, which is the other part of repentance, is exhibited to us in his actual arising and returning to his father's house. He assumed confidence to repair to his home, and firmly persuaded himself that his father would receive him, if not as a son, at least as one of his hired servants. “For,” says he, “I am no more worthy to be called thy son; make me as one of thy hired servants.” This plainly shows the sure hope he entertained, that his father would yield to his entreaties, and receive him into his favor.
5. And now I come, thirdly, to draw the character of the paternal heart of God, set forth in the parable.
I. When the son was yet a great way off, his father saw him. Behold the prevenient mercy of our Heavenly Father, who graciously looks for his prodigal children. Ps. 79:8; Isa. 30:18, 19; Ps. 32:8.
II. And was moved with compassion. Hereby is represented his mercy waiting to be gracious to us.
III. And ran and fell on his neck. Here is mercy receiving into favor.
IV. And kissed him. This exhibits mercy ready to administer consolation to the returning sinner. Micah 7:19; Isa. 66:13.
V. Bring forth, says he, the best robe, and put it on him (Isa. 61:10). This has relation to Christ, and points out his righteousness, and justifying grace. Rom. 8:33.
VI. And put a ring on his hand. Hereby is signified the Holy Spirit, the pledge of sonship (Gal. 4:6; Eph. 1:5), the seal of intimate favor and union; and it also represents to us the espousing mercy of the Lord.
