Our motives in life aren't supposed to be selfish and always looking for our best. However, when we submit to God and follow his ways it is for our best and he promises to reward us for it. I especially like the promise in Psalm 37 verse 4: "Take delight in the Lord, and he will give you your heart's desires." Delighting in God can't be a put-on act of singing certain songs or praying the right words of praise. Rather, delighting in God must flow from a heart of genuine love and adoration of God.
