I had to ponder this question a bit.
There are 150 chapters to this beloved book.
After careful consideration I chose Psalm 139. It begins with O Lord, you have searched me and you know me. You know when I sit and when I rise; you perceive my thoughts from afar. "
"I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well... all the days ordained for me were written in your book before one of them came to be...
Search me, O God and know my heart; test me and know my anxious thoughts. See if there is any offensive way in me and lead me in the way everlasting." vs. 14 - 16 - 23 & 24. (NIV)
Thank you for letting me share a favorite Psalm with you. Hope if you have one - you will share too!
Have a wonderful week.
