Luke 15:20

And he arose
This shows that his resolution to arise was not of nature, but of grace, by its being put into execution; for it was made and executed, not in his own strength, but in another's. He did not confer with flesh and blood; nor listen to discouragements which might present; as the distance of the way, the danger in it, the cold reception, if not rejection, he might expect from his father: but he arose immediately; he arose and stood upon his feet, in obedience to the heavenly call, being assisted by divine grace; he arose, and quitted the far country, the citizen, swine, and husks, and denied both sinful and righteous self;

and came to his father;
his own father; "the father of himself", as in the Greek text, who was so before he came to him; a sense of which he had, and was what encouraged him the rather to go to him: and this coming to him denotes a progression towards him; for as yet he was not come to him, but was at some distance, as the next clause expresses; and means not so much attendance on ordinances, as some inward secret desires after God:

but when he was yet a great way off.
This is not to be understood of his state of alienation from God, which is before signified by his being in a far country; but the distance he observed, as conscious of his vileness, and unworthiness; and the humility he expressed on a view of himself; and a sense he had of his need of divine grace: and which is grateful to God; he looks to such that are of an humble, and of a contrite spirit, and dwells among them, and gives more grace to them:

his father saw him;
he saw him when in the far country, spending his substance with harlots, and in riotous living; he saw him when among the swine and husks; he saw him when he came to himself, and all the motions and determinations of his heart; he saw him in his progress towards him, and looked upon him with an eye of love, pity, and compassion, as it follows,

and had compassion:
God is full of compassion, and pities him, as a father does his children; yea, as a woman's heart of compassion yearns after the son of her womb: he had compassion on him, and his heart of pity moved towards him, he being as one grieved in spirit for his sins, and wounded with a sense of them, and wanting a view of pardon, as starving and famishing, and as naked, and without clothing.

And ran;
to him, which shows the quick notice God takes of the first motions of his own grace in the hearts of sensible sinners; the speedy relief he gives to distressed ones; and this points out his preventing grace and goodness.

And fell on his neck;
expressive of the strength of his affection to him, ( Genesis 45:14 ) ( 46:29 ) ( Acts 20:37 ) and of his great condescension and grace to fall on that neck which had been like an iron sinew, so stiff and rebellious; though now, through divine grace, was made flexible and pliable, and subject to him, and willing to bear the yoke, and to do whatever he would have him; and this was grateful to his father:

and kissed him;
as a token of love; and as owning the relation he stood in to him; as a sign of reconciliation and friendship; and was an admission of him to great nearness to his person; and an application and manifestation of great love indeed to him; and a strong incentive of love in the son to him again; see ( 1 John 4:19 ) .
