Proverbs 10:24

Because it is a righteous desire it is safe for God to grant it. It would be neither good for the man himself, nor for society at large, that such a promise should be made to the unrighteous. Let us keep the Lord's commands, and He will rightfully have respect to our desires.

When righteous men are left to desire unrighteous desires, they will not be granted to them. But then these are not their real desires; they are their wanderings or blunders, and it is well that they should be refused. Their gracious desires shall come before the Lord, and He will not say them nay.
