"Delight yourself in the Lord and He will give you the desires of your heart." (Psa;m 37:4)
I was thinking of this verse only this morning, in connection with the "name it and claim it" faith movement. Too often this verse is misapplied to say that God will give us anything we want.
But what I believe it says is that if we delight in Him, He will give us new desires. The actual desires of our hearts will come from Him. Worldly desires come from a heart of stone, but when He gives us a new heart, one of flesh, He will also give us new desires. As we become more and more conformed to His likeness, the desires of our hearts should become closer and closer to His own desires.
It is my constant prayer that my will would conform to His, rather than me expecting His to conform to mine.
