Baptism is an act of faith whereby the penitent sinner calls upon the name of the risen Lord Jesus to be saved.

Jesus took John’s baptism of repentance for the forgiveness of sins and filled it with new and eschatological significance

The events in the book of Acts make it clear that baptism was understood as an essential part of conversion.

From the NT epistles passages on baptism we see that all the blessings of salvation are associated with baptism by faith.
