So often we try to figure out what heaven will be like? What does it look like? What will God and Jesus look like? Will they be One or separate? And finally what will we look like? Will we basically be the same, or a rejuvenated, better version of our previous bodies. Will we be the same age as when we died, or go back to our invincible youth with a full head of hair. I am particularly interested in that question. Finally, how can today's passage help to answer these questions or not?
I think the first thing we could deduce is that our resurrected body will be different from what we experience here. He says we will not have a natural body but a new spiritual body. What does that mean? I am not sure. When I think of spiritual I think of something you cannot see. Like the Holy Spirit. It blows where it wills and you feel its power but He cannot be seen. Or maybe since the Holy Spirit is a person, we will see him too.
I am reminded of Jesus when he appeared to his disciples and he said, "do not hold on to me because I have not yet ascended to my Father". It would seem like there was something different from his body after the resurrection. Jesus also said he would come back in great and promised glory. So it says today we are sown in dishonor but raised in glory. Maybe there is another clue in what Paul says to the Romans, "And if the Spirit of Him whose raised Jesus from the dead is living inside of you, he who raised Christ from the dead will also give life to your mortal bodies because of His Spirit who lives in you."
So what we will look like in heaven will certainly have to do with the Holy Spirit, who will raise us from the dead when we die. Yet, despite all of these ideas, at the end of the day we really don't know exactly what we will look like in heaven. All we know is that we are going to be there a long time so I am sure God has something planned better than we could ask or imagine.
1 Corinthians 15:42-49
42 So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; 43 it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; 44 it is sown a natural body, it is raised a spiritual body.
If there is a natural body, there is also a spiritual body. 45 So it is written: “The first man Adam became a living being”; the last Adam, a life-giving spirit. 46 The spiritual did not come first, but the natural, and after that the spiritual. 47 The first man was of the dust of the earth; the second man is of heaven. 48 As was the earthly man, so are those who are of the earth; and as is the heavenly man, so also are those who are of heaven. 49 And just as we have borne the image of the earthly man, so shall we[b] bear the image of the heavenly man.
