Paul repeatedly says, “no longer.” He reminds us that we “no longer” belong to the world, but to Christ. He claims that “[we] no longer live, but Christ lives in [us]. The lives [we] now live in the body, [we] live by faith in the Son of God, who loved [us] and gave Himself for [us].” We are “no longer” separated from God the Father but are brothers of Christ, and therefore sons of the living God. We “no longer” live as the Gentiles do, in the futility of their thinking.
Whereas “once [we] were alienated and hostile in [our] minds because of [our] evil actions, now [Christ] has reconciled [us] by His physical body through His death, to present [us] holy, faultless, and blameless before Him.” (Colossians 1:21-22) We are “no longer” dead in our sins, but are alive in the righteousness that comes through Christ.
