"For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day."
2 Timothy 1:12
The confidence that I hear is Paul's voice is amazing. "I am not ashamed: for I know whom I have believed..." Perhaps more of us need to know whom we have believed. Paul's confidence came from knowing God. Maybe if we knew God better our confidence in Him would be stronger.
