“And that ye put on the new man, which after God is created in righteousness and true holiness.”
King James Version (KJV)
4:24 The new man - Universal holiness. After - In the very image of God.
Eph 4:24 That ye put on the new man. He who has a new mind within him is a new man. He who is born anew, "of water and of the Spirit" (Joh 3:5), is newly created in righteousness and true holiness. This is still part of what they were taught (Eph 4:21). The new creation described took place at conversion.
