I have to serve the Lord, not belly nor health,

I have to serve the Lord, not belly nor health, For I am of Him, His precious blood redeemed; I have to serve the Lord, not fame nor wealth, May Spirit of life, to His service lead. If I gained the world and the things therein, Still to me is grief and vain. I have to serve the Lord, His pleasure win, And His fullness I thus gain.
