The Greek word used here for resurrection means 'a standing or rising up.' The resurrection is a major theme of New Testament teaching. Out of the 13 sermons in the book of Acts, 11 stress or simply mention the resurrection.
Man consists of three parts - a spirit, a soul, and a body (1 Thessalonians 5:23). The body is mortal while the spirit and soul are immortal. At death, man's body goes through the decomposition process and returns to its original elements.
At the resurrection, man's departed soul and spirit are called forth from either heaven or hell. The material elements of the body are raised up, reassembled, and united with the spirit and soul. Thus, we have the complete personality of the individual reconstituted. Everyone will be resurrected - some to life, and some to damnation.
The hope of the believer is the resurrection unto life. The natural, earthly, terrestrial, corrupt, weak, mortal, vile body is said to be raised, changed, and fashioned into a spiritual, heavenly, celestial, in-corrupt, glorious, powerful, and immortal body. This is the completion of everything that has been purchased for us in Christ.
Paul said in 1 Corinthians 15:12-17 that if there is no resurrection, then our faith is vain, and we are yet in our sins. It is the resurrected life of Jesus that brings spiritual life into us and the resurrection of the body that brings physical regeneration, reconstituting us into the very image of God. The transformation from the old physical condition to our new glorified bodies will be a huge difference, but the power of God can accomplish it easily. If the Lord can work that miracle, then surely, He can heal our bodies and free us from other bondage.
