I believe the resurrection happens at death
In ancient Egypt, Pharaohs drove their slaves to build huge pyramids to house their dead bodies. They filled these tombs with immense treasures of gold and all kinds of utensils that might be of service in their coming life. They cultivated the art of embalming, so that their bodies could be preserved for thousands of years with the least possible amount of decay. It's as if they thought that by taking such elaborate precautions, they could be prepared for the life to come. Apparently, they believed that their souls would one day return into those mummified bodies, and they wanted everything to be ready.
This is a stark contrast with the attitude expressed by Jesus. One of His disciples asked him, "Let me first go bury my father." Jesus said, "Follow me, and let the dead bury their dead" (Matthew 8:21-22, Luke 9:59-60). For Jesus, the dead body was of no consequence.
For Christians, the focus is not meant to be on the body that has died, but on the spirit that rises into the coming life. For two thousand years, Christians have been nourished by the hope that their loved ones who have died are happy in heaven with the Lord, not lying cold and dead in the ground. Nevertheless, some people believe that the resurrection will be a resurrection of the physical body that lies in the grave, and that when a person dies the soul remains unconscious for years or centuries until Christ comes again and brings all the bodies out of the grave and reawakens the souls that are sleeping within those bodies. Yet it is not only more comforting to picture a person rising immediately into the next life after death, but it is also more in keeping with the teachings of the Bible.
We Rise Soon after Death
Jesus tells of a poor man Lazarus and his rich neighbor who both died. The rich man ended up in hell, while Lazarus went up to heaven. (Luke 16: 22-24) Both of them came into the next life immediately after death. There was no hint here of a long wait to come back into their bodies, for the rich man's brothers were still alive on earth.
When Jesus was on the cross He promised one of the thieves, "Today you will be with Me in paradise" (Luke 23:43). Jesus did not say, "Just wait twenty centuries or more, and I will fix up your body again."
Since we rise immediately after death, people who have died are in the spiritual world, and they can be seen by those whose spiritual sight is open. For example, when Peter, James and John had their eyes opened to see Jesus in His glory, they also saw
Moses and
Elijah, who were clearly not in their graves. When Saul went to the witch of En Dor, he spoke with the spirit of
Samuel who appeared as an old man (1 Samuel 28: 3-19), and Lazarus found himself in the bosom of
Abraham in heaven (Luke 16:22-24). In fact, when Jesus said to the Sadducees that the God of Abraham, Isaac and Jacob is the God of the living, not the dead, the clear implication is that Abramam, Isaac and Jacob had
already risen from death into life (Matthew 22:31-32; Mark 12:26-27; Luke 20:37-38). He is "the God of the Living," not "the God of the dead who will centuries later come back to life."
Angels have sometimes appeared to people whose eyes were opened to see them. Very often, the Bible says that these angels are people. For example, we read that three
men appeared to Abraham (Genesis 18: 2), and that when Jacob wrestled with an angel he wrestled with a
man (Genesis 32: 24). Likewise, the angels were
people who appeared to Joshua (Joshua 5: 13-14), Manoah and his wife (Judges 13: 6-11), Ezekiel (Ezekiel 9: 2-3,11; 10: 2-3,6), Daniel (Daniel 9: 21; 10: 5; 12: 6-7), Zechariah (Zechariah 1:8,11), and the women at the sepulcher (Mark 16: 5; Luke 24: 4). The Bible says these angels were
people, and clearly none of them were still in the grave.
There Is a Spiritual Body
The Bible teaches that we rise with a different body than the one that is placed in the grave. "There is a natural body, and there is a spiritual body" (1 Corinthians 15: 44). The natural body is what is "sown" in the grave, and the spiritual body is what is raised up (1 Corinthians 15: 37, 42-44). People on earth have an earthly body, while people in heaven have a spiritual, heavenly body (1 Corinthians 15: 46-49). The fact that people in the spiritual world have a spiritual body is evident from the appearance of angels mentioned above. For example, Saul recognized Samuel after his death because he had a body similar to the body he had on earth. Clearly it was Samuel's
spiritual body, since his physical body was still in grave, and it was his spirit (1 Samuel 28:13) that had risen and was conversing with Saul.
The fact that there is a spiritual body is also clear from the story of Lazarus and the rich man. After death Lazarus was in the
bosom of Abraham; the rich man lifted his
eyes, and asked that Lazarus might dip his
finger in water to cool his
tongue (Luke 16: 22-24).
The body we have in the spiritual world is not the body that we put into the grave. The Bible says that our physical body is corruptible and mortal, which means that it does not last, but rots and dies. "Flesh and blood cannot inherit the kingdom of God; neither does corruption inherit incorruption" (1 Corinthians 15: 50). "We brought nothing into this world, and it is certain we can carry nothing out" (1 Timothy 6:7). When we go to our eternal home "then the dust will return to the earth as it was, and the spirit will return to God who gave it" (Ecclesiastes 12:5, 7; compare Genesis 3:19). So our earthly body cannot go to heaven, but when we put off our physical body, our corruptible and mortal life is changed into an incorruptible and immortal life (1 Corinthians 15: 53-54). Evidently when Paul said this, some people were wondering if everyone would sleep a long time in the grave before the resurrection, for Paul reassures people that we will
not all sleep, and that it will
not take ages but will happen immediately, in the twinkling of an eye, at the last trumpet, that is, when we die.
The Grain of Wheat
One of the ways that Jesus teaches us about the life after death is by saying, "Unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain" (John 12: 24; compare Matthew 13:31; Mark 4:31; Luke 13:19). This is very similar to the analogy that Paul uses: "Someone will say, 'How are the dead raised up? And with what body do they come?' Foolish one, what you sow is not made alive unless it dies. And what you sow, you do not sow that body that shall be, but mere grain—perhaps wheat or some other grain. But God gives it a body as he pleases, and to each seed its own body." (1 Corinthians 15: 35-38)
When a seed is put into the ground, the outer husk of this seed simply rots away. But within that seed is a germ of life that is raised up with a completely new plant or body around it. Paul says very clearly here that the body which is raised is not the body which is put into the ground. Furthermore, when the farmer plants his seed, it immediately begins growing. It does not remain dormant in the ground for centuries before a new life begins. Likewise, when our bodies are buried in the ground, the germ of life within each of us is immediately raised up clothed with a new body appropriate for the spiritual world.
Objections
Those who believe in a resurrection of the physical body may quote passages to support that belief, but an examination of those passages will show that this is not the teaching of the passages themselves, but is an assumption that is read into them.
What about Job's Prophecy?
Job says, "For I know that my redeemer liveth, and that he shall stand at the latter day upon the earth: And though after my skin [worms] destroy this [body], yet in my flesh shall I see God" (Job 19:25,26,
King James Version). Some people have assumed that the "latter day" means the end of the world, and that "worms destroying this body" means the body rotting in the grave. In fact, the original Hebrew does not mention either "worms" or "body". A more accurate translation is: "And after my skin is destroyed, this I know, that in my flesh shall I see God…" (
New King James Version).
Job was not talking about his body rotting in the grave, but about the fact that his skin was already virtually destroyed by the boils that covered him from head to foot (Job 2:7, 19:20). When he said, "in my flesh I shall see God," he was not talking about some future time when his body would be resurrected, but he was saying that he would see God before he died, while he was still alive in the body he had. At the end of the book of Job God
did appear to Job, and Job said, " I have heard of You by the hearing of the ear, but now my eye sees You" (Job 42:5). And so the prophecy was fulfilled, that in his flesh he would see God. We can also see that God redeemed him at that time, for we are told, "The Lord accepted Job. And the Lord restored Job's losses…. Indeed the Lord gave Job twice as much as he had before" (Job 42:9-10). The same chapter shows us what Job meant by "the latter day," for we read, "Now the Lord blessed the latter days of Job more than his beginning" (Job 42:12).
Taken in context, this passage says nothing at all about the resurrection of the physical body centuries later, yet it has been taken as a primary passage supporting that concept.
