Behold, Lord, an empty vessel that needs to be filled. My Lord, fill it. I am weak in faith; strengthen me. I am cold in love; warm me and make me fervent, that my love may go out to my neighbors. I do not have a strong and firm faith; at times I doubt and am unable to trust You altogether. O Lord, help me. Strengthen my faith and trust in You. In You I have sealed the treasure of all I have. I am poor; You are rich and came to be merciful to the poor. I am a sinner; You are upright. With me, there is an abundance of sin; in You is the fullness of righteousness. Therefore I will remain with You, of whom I can receive but to whom I may not give. Amen.
Martin Luther, from "For All the Saints," page 190
