Question: "Will there be sex in heaven?"
Answer: In Matthew 22, the Sadducees, in an attempt to discredit Jesus, came to Him with a question regarding marriage and the resurrection. Jesus answered them with these words: “At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven” (verse 30). Jesus teaches here that marriage is a relationship to be enjoyed in this life, but it will not carry forward into the next life. While we do not lose our identity in heaven (Luke 16:23), we will not hold the same relationships that we do on earth. Our existence will be quite different from what we are used to here. The fact that there is no marriage in heaven implies at least two other things: 1) There will be no procreation in heaven; the number of the redeemed is set, and, with no death, there will be no need to propagate the race. 2) There will be no sexual intercourse in heaven. The appetites and desires of this world will give way to higher and infinitely more gratifying delights in the world to come.
For centuries, the temple and its sacrifices were at the heart of worship, but once Christ came and offered Himself as the ultimate sacrifice, the temple system and its sacrifices were no longer needed (John 4:22-23). They were “copies of the heavenly things,” and the earthly temple was only “a copy of the true one” in heaven (Hebrews 9:23-24). In the same way, the marriage relationship is a picture of our relationship with Christ (Ephesians 5:31-32). Once we are present with Christ, the illustration will no longer be needed. We will have the reality, which is far better than any earthly representation. This is why Jesus is called the Bridegroom, the Church is called His Bride, and our celebration in heaven is called the Wedding (John 3:29; Matthew 22:1-14; Revelation 19:7-9).
