This is a worship song that I played in our church. It's based on Psalms 63:1-4 (NCV)
1 God, you are my God. I search for you. I thirst for you like someone in a dry, empty land where there is no water. 2 I have seen you in the Temple and have seen your strength and glory.
3 Because your love is better than life, I will praise you. 4 I will praise you as long as I live. I will lift up my hands in prayer to your name.
