And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; And you, being dead in your sins - See the notes on Ephesians 2:1, etc.
The uncircumcision of your flesh - This must refer to that part of the Colossian Church which was made up of converted heathens, for the heathens alone were uncircumcised.
