I Corinthians 15:10

ESV

But by the grade of God I am what I am, and His grace towards me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God that is with me. 

1 Corinthians 15:10 

Amazing grace! How sweet the sound that scared a wretch like me! I was was lost but not am found; was blind but now I see.  

- John Newton
