God will give you anything you "Desire"?

We often quote Psalms 37:4 as our "guarantee" that God is going to come through with granting our desires. After all, that verse says: "Delight yourself in the Lord and he will give you the desires of your heart." We want our desires and we want them now. But we need to look more closely at that verse and the one that follows. Could it be that God is saying once we delight ourselves in Him, He will place in us certain desires that He will delight in granting? The verse that follows says: "Commit your way to the Lord, trust in him and he will do it" (verse 5). I believe God is saying "Delight yourself in Me and I will give you desires for what I desire, and then I'll gladly grant them."
