Psalm 40: 1-3
I waited patiently for the Lord: and He inclined unto me, and heard my cry
He bought me up also out of an horrible pit, out of the miry clay, and set my feet upon a rock, and established my goings.
And He hath put a new song in my mouth, even praise unto our God: many shall see it and fear, and shall trust in the Lord.

Many years ago as a back-slidden Christian, I was in that pit, sunk in the miry clay. He took me, cleaned me and set me on firm ground. He didn't give up on me :)
