What return can I make to God

“What return can I make to Yahweh for His generosity to me? I shall take up the cup of salvation and call on the Name of Yahweh.” Psalm 116:12-13

"What can the pardoned sinner, or what can those who have been delivered from trouble or distress, render to the Lord for his benefits? We cannot in any way profit him. Our best is unworthy of his acceptance; yet we ought to devote ourselves and all we have to his service. I will take the cup of salvation in token of thankfulness to God, and rejoice in God's goodness to me. I will receive the cup of affliction; that cup, that bitter cup, which is sanctified to the saints, so that to them it is a cup of salvation; it is a means of spiritual health. The cup of consolation; I will receive the benefits God bestows upon me, as from his hand, and taste his love in them, as the portion not only of my inheritance in the other world, but also in this."
