People often underestimate who the Spirit is and what the Spirit does. Minister Aaron Hill tells listeners that the Spirit is a person, a member of the Godhead! His work is much more amazing that what we think. When we see the Spirit work, it is amazing, not limited to a tiny box. God's work is always outside the box we tend to put Him in. Sanctification is the most important job of the Spirit, and in 2 Thess. 2:13-14, we find that sanctification is linked to salvation. In Heb. 10, we learn that the goal of animal sacrifice was to take away the consciousness of sins, to change the conscience and turn it to good, but animal sacrifices did not last. They had to be made over and over. Heb. 10:10 reveals that Jesus' sacrifice on the cross did what animal sacrifices could not do: we are "sanctified through the offering of the body of Jesus Christ once for all." God doesn't want to just cleanse us; he wants to change us. If we reject the change, we reject the cleansing. It is an insult to Christ to neglect the change he offers.
