The Only Way To Pay God Back

What shall I render to the LORD for all his benefits to me? I will lift up the cup of salvation and call on the name of the LORD ...
Psalm 116:12, 13

Overwhelmed by all the benefits he has received from the LORD, the psalmist asks how he can render back to the LORD what He has given him, how he can return what the LORD has given so generously, how he can pay God back.

And he provides for us the only answer that doesn't commit blasphemy by dishonoring God and nullifying grace. The very cup of salvation that God has placed in his hands and filled with grace, he will lift up and cry out to God to fill with more and more grace that leads to salvation.

On the day I called, you answered me; my strength of soul you increased.
Psalm 138:3

So what does David do in response?

He pleads with God for more strength and deliverance:

Do not forsake the work of your hands.
Psalm 138:8

The only way to pay God back is to go deeper and deeper into debt by continuing to call on Him and, in so doing, let Him display Himself as the always greater grace-Giver. And nothing delights Him more. He gets the glory. We get the help, satisfaction, and joy. God is most glorified in us when we are most satisfied in Him. What a God, infinitely worthy of our love!

[He is not] served by human hands, as though he needed anything, since he himself gives to all mankind life and breath and everything.
Acts 17:25
