Let us consider the Holy Spirit who is
the one who sanctifies us. The Latin word
Sanctus (sanctuary, sanctification) is where we
get our English word holy (set-apart). We are
made holy not through our own power or
effort to be, or do better. We are made holy
through the power of the Holy Spirit who
produces all that is good (fruit of the Spirit)
within us. Left to our own devices, we will
produce the "acts of the flesh" which are
opposed to the fruits of the Spirit.
