The marvel is not me

“The marvel of the Redemptive Reality of God is that the worst and the vilest can never get to the bottom of His love. Paul [the Apostle] did not say that God separated him to show what a wonderful man He could make of him, but “to reveal His Son in me.”

Oswald Chambers

February 3

This quote would seem to flow counter to the river of Christian books that  promote the idea of becoming all we can be. Is it the same thing? Or have we moved the mark some how? PH
