Does God not perhaps use our physical bodies to create our heavenly bodies?, In all of Scripture when those that were dead were raised their bones must have been resurrected and new flesh created. When Jesus was raised what happened to His fleshly body?.....you won't find His bones as I believe they have been transformed. I believe God actually changes the flesh from corruptible to uncorruptable. Cremation has bugged me for a long time, but surely God can recreate bones as He can with flesh, science says that matter cannot be destroyed.
Obviously, my response is a guess. But you are right, Jesus' physical body was obviously transformed into His spiritual body, and this cannot happen once one is cremated, so any theory must account for both. My personal belief is that your spirit determines your body. For this earth, the hand of God molded the earth to make a suitable temporary earthly body for you. When you rise, your spirit makes a suitable body for heaven. Since Jesus had the physical body laying pretty much non-deomposed on the earth, the spiritual body "picked up" and manifested into the physical, as long as He remained here. The same thing would happen to us, if after the resurrection, we "time-travelled" backward into this era. Our spiritual body would grab whatever physical matter/energy is necessary to gain for itself a suitable vehicle for this space-time. In fact, this is how Moses and Elijah's bodies were transformed during the transfiguration incident on the mountain, when they talked with Jesus.
Science also assumes that experiments are repeatable. This requires the assumption that physical laws do not change during the time between repetitions. But faith is the substance of things unseen, therefore faith can change things. Science is thus limited in its use only to where faith is not operating in its full capabilities.
The nature of spirit is to select the best organization of mind and flesh. This is the general prinicple implied in Rom. 12:2.
