I.O.U.S. from God?

I saw this on Twitter this morning from John Piper:

I.O.U.S. - Incline my will (Psa 119:36). Open my eyes (Psa 119:18). Unite my heart (Psa 86:11). Satisfy my soul (Psa 90:14).

God owes us nothing, but He gives us EVERYTHING.

This is my prayer for today, that the Lord would incline my will, open my eyes, unite my heart, and (what I struggle with most of all), satisfy my soul.

Amen.
