³ Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
⁴ Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
⁵ For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
⁶ Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
⁷ For he that is dead is freed from sin.
⁸ Now if we be dead with Christ, we believe that we shall also live with him:

Once you have crucified your old ways (sins) when you REPENT, the dead person must be buried. BAPTISM, a watery grave, corresponds to the burial and resurrection of Christ. This is the Biblical way to be born again, a new person free from sin. (Galatians 5:24; II Timothy 2:11)
