There is a process going on in us believers.
Since the day the Holy Spirit came to dwell in us, He has been at work with perfect wisdom and supernatural power to renew and transform our character, to some extent, our personality.
Our outward man, this mortal body with its natural weakness and sinful ways was doomed to death and is "wasting away" even now. Yet a new life dwells within this clay jar, and that life is constantly at work having a profound effect on the body which contains it.
The Holy Spirit is working a renewal, a renovation, the manifestation of God in and with us.
Real estate developers do something similar.
They buy a piece of property that is terribly run down, seemingly useless, without much value to the naked eye, and reform it completely, from the inside out.
With great skill and vision, they know what to keep, what to get rid of, what part of the property needs renovation, refurbishing, or complete rebuilding.
So it is with God and us...
