How the body is constituted?

John 3:5

Jesus answered, “I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit. 

Romans 6:3-5

3 Or don't you know that all of us who were baptized into Christ Jesus were baptized into his death?

4 We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.

5 If we have been united with him like this in his death, we will certainly also be united with him in his resurrection.

Galatians 3:26-27

26 You are all sons of God through faith in Christ Jesus,

27 for all of you who were baptized into Christ have clothed yourselves with Christ.

Colossians 2:11-17

11 In him you were also circumcised, in the putting off of the sinful nature, not with a circumcision done by the hands of men but with the circumcision done by Christ,

12 having been buried with him in baptism and raised with him through your faith in the power of God, who raised him from the dead.

13 When you were dead in your sins and in the uncircumcision of your sinful nature, God made you alive with Christ. He forgave us all our sins,

14 having canceled the written code, with its regulations, that was against us and that stood opposed to us; he took it away, nailing it to the cross.

15 And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.

16 Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day.

17 These are a shadow of the things that were to come; the reality, however, is found in Christ.
