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, Psa 4:6, Psa 4:7. 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.

The desire accomplished is sweet to the soul,.... Whether the desire be after riches and honour, after wisdom and knowledge; or after the best things, the knowledge of God, and communion with him; an interest in Christ, and the blessings of his grace, as pardon, righteousness, &c. and a right and title to eternal glory and happiness, and the enjoyment of that: and how sweet are these things the soul desires, when they are possessed! see Pro 13:12; such are "the desires of the godly", as the Septuagint render the word;

but it is abomination to fools to depart from evil; they cannot bear the thoughts of parting with their lusts; they are so delightful to them, not knowing anything of the sweetness of the things before mentioned; and which they can never enjoy without departing from sin, to which they are exceedingly averse.

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