Who are the 'uncircumcision of your flesh' in Colossians 2?
The 'uncircumcision of your flesh' in Colossians 2 refers to pagan Gentiles. Paul writes it describes their pre-salvation existence as those dead in sins. It marks their condition apart from Christ before He made them alive together with Him, having forgiven their trespasses.
Les explains that Colossians 2 addresses pagan Gentiles who were dead in their sins in their pre-salvation existence, described as the uncircumcision of their flesh. When Christ died, believers died with Him; when He arose, they arose to newness of life. God quickened them together with Christ, making them alive and forgiving every trespass—past, present, and future. Les stresses that when Christ died, He died for all the world's sins, tasting death for every man. Scripture cannot lie, and God holds us accountable to believe His Word; that faith pleases Him, for without faith it is impossible to please Him.
