Paul want to be sure the new believers in Asia Minor know where they came from before they came to Christ. It was spiritual death. Then he follows up with the power of God that raised them to life with Christ, and seated them with Him in the Heavenlies. Mercy opened the door, grace was a free gift, and faith (belief plus trust) drew that free gift into the spirits and souls of the new believers. Paul finishes with the reality that God created us with His workmanship, and set us on a path of good works in His Name.
