Philippians 3:13-14King James Version (KJV)
13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,14 I press toward the mark for the prize of the high calling of God in Christ Jesus.
I like St. Paul. He's very reassuring, clear, and smart. I listen to these epistles every day. I can't get enough of hearing how I'm acceptable in the beloved, and encouraged to proceed with lots of help.
