There are only two things which I am sure of

(Letters of John Newton)

When I was young, I was sure of many things.
But now that I am old, there are only two
things which I am sure of:
  One is that I am a miserable sinner!
  Secondly, that Christ is an all-sufficient Savior!

He is well taught—who learns these two lessons.

"This saying is trustworthy and deserving of full
 acceptance: 'Christ Jesus came into the world
 to  save sinners'—and I am the worst of them!"
     1 Timothy 1:15
