Does the body go to heaven?

John 3:13 makes it perfectly clear that no one can ascend into Heaven except He (Jesus) who came down from Heaven.

Human minds are powered by the spirit in man (Job 32:8). Think of this like a CPU and Memory of a modern computer. Everything the senses are involved with are stored. All our Words and deeds too. Solomon was inspired to write in Ecclesiastes 10:9, "Then shall the dust (human body) return to the earth as it was and the spirit (in man) shall return unto God who gave it."

Though the Scripture does not tell us why the spirit returns to God, we can deduce that it awaits the revival of mankind in the Great White Throne Judgement process when each of us who partake of this resurrection are given a new body and stand before the Lord for judgement. A body without the spirit of man within would not need to go through this process. It seems rational to assume the spirit being safeguarded by God from all evil spirits, is returned to the new body to re-establish the person it was. Then the judgement process may proceed.

Another thought:

1 Corinthians 15:50 says: "Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption." (KJV)
