Proverbs 13:12
12 Hope deferred maketh the heart sick: but when the desire cometh, it is a tree of life.
Note, 1. Nothing is more grievous than the disappointment of a raised expectation, though not in the thing itself by a denial, yet in the time of it by a delay: Hope deferred makes the heart sick and languishing, fretful and peevish; but hope quite dashed kills the heart, and the more high the expectation was raised the more cutting is the frustration of it. It is therefore our wisdom not to promise ourselves any great matters from the creature, not to feed ourselves with any vain hopes from this world, lest we lay up matter for our own vexation; and what we do hope for let us prepare to be disappointed in, that, if it should prove so, it may prove the easier; and let us not be hasty. 2. Nothing is more grateful than to enjoy that, at last, which we have long wished and waited for: When the desire does come it puts men into a sort of paradise, a garden of pleasure, for it is a tree of life. It will aggravate the eternal misery of the wicked that their hopes will be frustrated; and it will make the happiness of heaven the more welcome to the saints that it is what they have earnestly longed for as the crown of their hopes.
Proverbs 13:19
19 The desire accomplished is sweet to the soul: but it is abomination to fools to depart from evil.
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. iv. 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.
