2 Corinthians 4:16 For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.
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, and even our physical body. 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 renewal, 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. He knows everything that comprises our life from the moment of conception; our gifts, abilities, strengths, weaknesses, wounds, and all the characteristics of our personalities. And He wants to completely renovate us according to the vision He has for our lives, which is much greater than we can imagine. He has purchased the "property" of our lives, with His blood, and His Holy Spirit is powerfully and skillfully at work developing the Lord's "real estate"!
Your life is in good hands. Your Developer knows exactly what He's doing with you. You might be a little tired or discouraged, run down, or even wrecked in some places, but soon, you will sense, once again that He is building, renovating, and renewing you in the best possible way...for eternity.
