When circumstances lead us to the end our ourselves, when we reach the limit of our power and our ability and we finally look up and cry out to God--that is grace. Praise Him for those times for He's teaching you to lean on and trust in Him. You can be sure of this: He is faithful, even in our faithlessness, and He is worthy of our trust.

He brought me up out of the pit of destruction,
out of the miry clay,
And He set my feet upon a rock making my footsteps firm.
He will put a new song in my mouth, a song of praise to our God;
Many will see and fear
And will trust in the Lord.
Psalm 40:2-3

2 Timothy 2:13
