St. Paul reminds the Gentile Christians of the terrible way of life that they walked when they lived under idolatry. Such a life was nothing but futility, darkness, ignorance, impurity, and hardness of heart. Instead, now they have received Christ and His truth. Baptized into Him, they have put off the old self, that is, the sinful nature. Through the work of the Spirit, their minds are renewed and they put on the new self, created after the image of God in His righteousness.

Rev. David Boisclair, pastor at Our Redeemer Lutheran Church in Overland, MO, joins host Rev. Timothy Appel to study Ephesians 4:17-24.

"One Lord, One Faith, One Baptism” is a series on Sharper Iron that goes through the epistle to the Ephesians. St. Paul highlights the salvation that God has given to His whole Church by His grace through faith. Because God has given His people this new life in Holy Baptism, we live in thanksgiving to Him as members of one body.
