“Delight yourself also in the Lord and he will give you the desires of your heart.” (Psalm 37:4)
Transformed desires
The above promise is well quoted. Even so, it’s very much misunderstood by many who believe it is a way to get anything they desire from God. First of all, the human heart is desperately wicked and often desires things God condemns (Jer. 17:9). For instance, God won’t give you someone else’s spouse or give you a truckload of gold bars. He only gives things that are in line with His Word—what's best for you or what’s needed to enable you to perform the assignment He’s created you for. So, what actually happens when you delight yourself in the Lord? He transforms your desires into what they should be! Then, with new desires, you receive the corrected but perfect desires of your heart! It’s a wonderful thing to finally desire the right things in line with God’s very best!
Therefore
The next verse, right after the one at the top, tells you what to do. Not only must you make God your delight, but you must also commit to and trust Him. Then God will act! Wow, and watch what He will do in your life!
“Commit your way to the Lord; trust in him, and he will act.” (Psalm 3:5)
