Romans 6:4-7

We have therefore been buried with Him through baptism into death, so that just as Christ was raised from the dead through the glory and power of the Father, we too might walk habitually in newness of life [abandoning our old ways]. For if we have become one with Him [permanently united] in the likeness of His death, we will also certainly be [one with Him and share fully] in the likeness of His resurrection. We know that our old self [our human nature without the Holy Spirit] was nailed to the cross with Him, in order that our body of sin might be done away with, so that we would no longer be slaves to sin. For the person who has died [with Christ] has been freed from [the power of] sin.
