Paul reveals in Colossians 2:11-15 that Christ alone is sufficient for our salvation and spiritual growth. Through our union with Christ, we experience spiritual circumcision where our old sinful nature is cut away, burial and resurrection with Him through baptism, and complete forgiveness of all our sins. God canceled the debt of our sin by nailing it to the cross, where Christ triumphed over all spiritual enemies. This passage teaches us that every blessing flows from our union with Christ, God gives new life to the spiritually dead, declares sinners not guilty through justification, and provides victory over defeated enemies.
