It seems to me that the underlying implication of this question is "What happens if there is no body to resurrect?" I think that Jesus, Himself, and the Apostle, Paul both addressed this issue. The religious leaders of the time asked Jesus a complicated question about marriage and resurrection, hoping, no doubt, to trip him up on some fine point of Jewish law.
"Jesus replied, 'The people of this age marry and are given in marriage. But those who are considered worthy of taking part in the age to come and in the resurrection from the dead will neither marry nor be given in marriage, and they can no longer die; for they are like the angels. They are God’s children, since they are children of the resurrection.'" (Luke 20:34-36, emphasis added)
And Paul said, "So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body. If there is a natural body, there is also a spiritual body. So it is written: 'The first man Adam became a living being'; the last Adam, a life-giving spirit. The spiritual did not come first, but the natural, and after that the spiritual. The first man was of the dust of the earth; the second man is of heaven. (1 Corinthians:42-47)
I believe that these passages are pretty conclusive evidence that the body which is raised on Resurrection Day will not be the same body that was buried in the ground when the person died. Therefore, cremation or burial does not seem to make a whole lot of difference to God.
