I Am Who I Am

As a Christian, it is difficult to read Psalm 139 and not come away knowing that God made us who we are. He knew us before we were formed. All of the quirks and the annoyances of our being as well as the wonderful qualities we possess, can be placed firmly at the feet of God himself. It is all His fault. It is all credited to Him. So why do we, so often, try to mold ourselves into something that we're not in order to blend in with everyone else?
