Colossians 2:11-15

11 In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. 13 And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, 14 by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. 15 He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him.

Note that Christ is the one who makes us alive together with him. The act of Baptism in association with being saved was necessary before all thing were fulfilled. Now as Christ dwells within us and we are in the new heavens and earth, the act of baptism, although not wrong, isn't necessary in "Paradise." In a covenental mindset, Christ now joins us into his people by circumcising our hearts.

Preston makes a great case for old-covenant circumcision equaling baptism. The Calvinistic concept of pedo-baptism isn't a scriptural stretch using this argument in their baptisms. While I agree with credo-baptism, how can we be dogmatic on an interpretation of scripture? Also, since Christ circumcises our hearts, in the New Covenant, not through baptism done by hands, but of Christ...the act of baptism is now a public sign of what Christ has accomplished through the wiping out of the Old Covenant.
