For as many [of you] as were baptized into Christ [into a spiritual union and communion with Christ, the Anointed One, the Messiah] have put on (clothed yourselves with) Christ.
Galatians 3:27 (AMP)
Every born again believer has been joined into a spiritual union and communion with Christ, meaning that our born again recreated spirit is of the same nature as Jesus—righteousness and true holiness. Nothing we can do in the flesh can undo who we have been made to be in Him. The more we accept this by faith and let it take root in our hearts, the more are we empowered to live rightly in this present world.
