The desire accomplished is sweet to the soul: but it is abomination to fools to depart from evil.

Wesley's Notes

13:19 Sweet - Whatsoever men earnestly desire, the enjoyment of it is sweet to them; therefore sinners rejoice in the satisfaction of their sinful lusts, and abhor all restraint of them.

Jamieson-Fausset-Brown Bible Commentary

19. Self-denial, which fools will not endure, is essential to success.

Matthew Henry's Concise Commentary

13:14. The rule by which the wise regulate their conduct, is a fountain yielding life and happiness. 15. The way of sinners is hard upon others, and hard to the sinner himself. The service of sin is slavery; the road to hell is strewed with the thorns and thistles that followed the curse. 16. It is folly to talk of things of which we know nothing, and to undertake what we are no way fit for. 17. Those that are wicked, and false to Christ and to the souls of men, do mischief, and fall into mischief; but those that are faithful, find sound words healing to others and to themselves. 18. He that scorns to be taught, will certainly be brought down. 19. There are in man strong desires after happiness; but never let those expect any thing truly sweet to their souls, who will not be persuaded to leave their sins. 20. Multitudes are brought to ruin by bad company. And all that make themselves wicked will be destroyed. 21. When God pursues sinners he is sure to overtake them; and he will reward the righteous. 22. The servant of God who is not anxious about riches, takes the best method of providing for his children. 23. The poor, yet industrious, thrive, though in a homely manner, while those who have great riches are often brought to poverty for want of judgment. 24. He acts as if he hated his child, who, by false indulgence, permits sinful habits to gather strength, which will bring sorrow here, and misery hereafter. 25. It is the misery of the wicked, that even their sensual appetites are always craving. The righteous feeds on the word and ordinances, to the satisfying of his soul with the promises of the gospel, and the Lord Jesus Christ, who is the Bread of life.

Matthew Henry's Whole Bible Commentary

Verse 19

This shows the folly of those that refuse instruction, for they might be happy and will not. 1. They might be happy. There are in man strong desires of happiness; God has provided for the accomplishment of those desires, and that would be sweet to the soul, whereas the pleasures of sense are grateful only to the carnal appetite. The desire of good men towards the favour of God and spiritual blessings brings that which is sweet to their souls; we know those that can say so by experience, Ps. 4:6, 7. 2. Yet they will not be happy; for it is an abomination to them to depart from evil, which is necessary to their being happy. Never let those expect any thing truly sweet to their souls that will not be persuaded to leave their sins, but that roll them under their tongues as a sweet morsel.
