Paul continues . . . sanctification through faith and baptism
makes one belong to God.
Romans 6:19, 22
I am speaking in human terms because of the weakness
of your nature. For just as you presented the parts of your
bodies as slaves to impurity and to lawlessness for
lawlessness, so now present them as slaves to
righteousness for sanctification. … But now that you
have been freed from sin and have become slaves of
God, the benefit that you have leads to sanctification, 
and its end is eternal life.
