Psalm 37:4 (KJV) Delight thyself also in the Lord: and he shall give thee the desires of thine heart.

Desires change over time. When I was young, I wanted to be old. When I was single, I wanted to be married. When I was in school, all I wanted was to graduate. We change too, as we receive the desires of our heart. Sometimes, we are grateful for answered prayers. Sometimes, we are grateful for unanswered prayers. Maturity changes our desires. Experience changes our desires. God changes our desires. The scripture says, "delight yourself in the Lord." When you delight yourself in the things that matter to God, your desires will align with the things of God. What is God's desire for your life? Who does God desire you to be? God's desires for you should work in tandem with your own personal desires.
