Randy Alcorn delves into the concept of resurrection bodies, emphasizing that our bodies will be transformed to be like Christ's glorious body. He highlights the physical nature of Christ's resurrection, showcasing how Jesus walked the earth in his resurrected body for forty days, interacting with his disciples in a normal, human way. Alcorn points out that Christ's resurrection body was suited for life on Earth, indicating that we too will be raised to come back to live on Earth, not just in an intermediate Heaven.

Not only do we know what our present bodies are like, we also have an example in Scripture of what a resurrection body is like. We’re told a great deal about Christ’s resurrected body, and we’re told that our bodies will be like his. The Lord Jesus Christ . . . will transform our lowly bodies so that they will be like his glorious body. (Philippians 3:20-21) Beloved, we are God’s children now; it does not yet appear what we shall be, but we know that when he appears we shall be like him, for we shall see him as he is. (1 John 3:2) And just as we have borne the likeness of the earthly man, so shall we bear the likeness of the man from heaven. (1 Corinthians 15:49) The difference between Adam and Christ is not that one was a physical being and the other wasn’t. It was that Adam was under sin and the Curse, and Christ was untouched by sin and the Curse. Jesus was and is a human being, “in every respect like us” (Hebrews 2:17), except with respect to sin. Though Jesus in his resurrected body proclaimed, “I am not a ghost” (Luke 24:39), countless Christians think they will be ghosts in the eternal Heaven. I know this because I’ve talked with many of them. They think they’ll be disembodied spirits, or wraiths. The magnificent, cosmos-shaking victory of Christ’s resurrection—by definition a physical triumph over physical death in a physical world—escapes them. If Jesus had been a ghost, if we would be ghosts, then redemption wouldn’t have been accomplished. Jesus walked the earth in his resurrection body for forty days, showing us how we would live as resurrected human beings. In effect, he also demonstrated where we would live as resurrected human beings—on Earth. Christ’s resurrection body was suited for life on Earth, not primarily life in the intermediate Heaven. As Jesus was raised to come back to live on Earth, so we will be raised to come back to live on Earth (1 Thessalonians 4:14; Revelation 21:1-3). The risen Jesus walked and talked with two disciples on the Emmaus road (Luke 24:13-35). They asked him questions; he taught them and guided them in their understanding of Scripture. They saw nothing different enough about him to tip them off to his identity until “their eyes were opened” (Luke 24:31). This suggests that God had prevented them from recognizing Jesus earlier, which they otherwise would have. The point is that they didn’t see anything amiss. They saw the resurrected Jesus as a normal, everyday human being. The soles of his feet didn’t hover above the road—they walked on it. No one saw bread going down a transparent esophagus when he swallowed. We know the resurrected Christ looked like a man because Mary called him “sir” when she assumed he was the gardener (John 20:15). Though at first she didn’t recognize his voice, when he called her by name, she recognized him (John 20:16). It was then that she “turned toward him.” Because modest women didn’t look male strangers in the eye, this phrase suggests that she hadn’t gotten a good look at him before. Jesus spent remarkably normal times with his disciples after his resurrection. Early one morning, he “stood on the shore” at a distance (John 21:4). He didn’t hover or float—or even walk on water, though he could have. He stood, then called to the disciples (John 21:5). Obviously his voice sounded human, because it traveled across the water and the disciples didn’t suspect it was anyone but a human. It apparently didn’t sound like the deep, otherworldly voices that movies assign to God or angels. Jesus had started a fire, and he was already cooking fish that he’d presumably caught himself. He cooked them, which means he didn’t just snap his fingers and materialize a finished meal. He invited them to add their fish to his and said, “Come and have breakfast” (John 21:12). In another appearance to the disciples, Christ’s resurrection body seamlessly interacted with the disciples’ mortal bodies (John 20:19-23). Nothing indicates that his clothes were strange or that there was a halo over his head. He drew close enough to breathe on them (John 20:22). On the other hand, though the doors were locked, Christ suddenly appeared in the room where the disciples were gathered (John 20:19). Christ’s body could be touched and clung to and could consume food, yet it could apparently “materialize” as well. How is this possible? Could it be that a resurrection body is structured in such a way as to allow its molecules to pass through solid materials or to suddenly become visible or invisible? Though we know that Christ could do these things, we’re not explicitly told we’ll be able to. It may be that some aspects of his resurrection body are unique because of his divine nature.††† By observing the resurrected Christ, we learn not only about resurrected bodies but also about resurrected relationships. Christ communicates with his disciples and shows his love to them as a group and as individuals. He instructs them and entrusts a task to them (Acts 1:4-8). If you study his interactions with Mary Magdalene (John 20:10-18), Thomas (John 20:24-29), and Peter (John 21:15-22), you will see how similar they are to his interactions with these same people before he died. The fact that Jesus picked up his relationships where they’d left off is a foretaste of our own lives after we are resurrected. We will experience continuity between our current lives and our resurrected lives, with the same memories and relational histories. Once we understand that Christ’s resurrection is the prototype for the resurrection of mankind and the earth, we realize that Scripture has given us an interpretive precedent for approaching passages concerning human resurrection and life on the New Earth. Shouldn’t we interpret passages alluding to resurrected people living on the New Earth as literally as those concerning Christ’s resurrected life during the forty days he walked on the old Earth?
