From 2 Corinthians

"My grace is sufficient for you." (2 Cor 12:9)

My, is, you: God did not say "My grace will become sufficient for you if you pray long enough, often enough, or correctly." And my prayers that sound like, "Lord, make Your grace feel sufficient for me" or "Please, God, help me to feel ok with your grace" mock His promise.

Trying to live in the reality of that promise is not easy. The underlying lesson for me is simply this: Stop trying to change God's facts into my hopes or prayers. Accept them as realities and they become every bit as powerful as I believe them to be.
