And baptism, which is a figure [of their deliverance], does now also save you [from inward questionings and fears], not by the removing of outward body filth [bathing], but by [providing you with] the answer of a good and clear conscience (inward cleanness and peace) before God [because you are demonstrating what you believe to be yours] through the resurrection of Jesus Christ.
I Peter 3:21
Go then and make disciples of all the nations, baptizing them into the name of the Father and of the Son and of the Holy Spirit…
We were buried therefore with Him by the baptism into death, so that just as Christ was raised from the dead by the glorious [power] of the Father, so we too might [habitually] live and behave in newness of life.
[Thus you were circumcised when] you were buried with Him in [your] baptism, in which you were also raised with Him [to a new life] through [your] faith in the working of God [as displayed] when He raised Him up from the dead.
