3 For we will put on heavenly bodies; we will not be spirits without bodies. 4 While we live in these earthly bodies, we groan and sigh, but it’s not that we want to die and get rid of these bodies that clothe us. Rather, we want to put on our new bodies so that these dying bodies will be swallowed up by life. 5 God himself has prepared us for this, and as a guarantee he has given us his Holy Spirit.— 2 Cor. 5:3-5 NLT

When God first made man in His image, He looked at what He had made and said “it is very good” (Gen 1:31). Decay and death were not known at this time.  Then sin came into the world and things were no longer “very good”.  Our bodies, along with all creation, started to deteriorate and eventually die.  Jesus came into the world as a man to redeem the fallen creation and restore it to the order that had been in the garden.  Jesus brought hope to a dying world.  He came that we might be made “new creations”.  Newness requires that we get rid of the old.  We are saved when we accept Jesus and our Spirits are renewed but we remain in a fleshly body in a sinful world.  The Spirit is being renewed day by day but the flesh is decaying day by day.

Our hope, the thing that makes Christianity different from anything else, is that we will one day leave these rotting, fleshly bodies and live in those heavenly bodies that God has created for each of us. Bodies that do not suffer pain and will not decay or die.  God has prepared and continues to prepare us for this transition. We have a guarantee of this that lives inside of us so that we are never alone or without hope.  Until the process is complete and Jesus comes again, we live hopefully and joyfully “looking unto Jesus, the author and the finisher of our faith”.
