Even though I didn't give the message this week I'll try to answer the question we received regarding the passage:
Q – If marriage is so important to God, and he created it, why will there be NO marriage in heaven? Matthew 22:29-30.
A – I don’t know the answer, but I think God may have given us a little clue in Ephesians 5.
“Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.” This mystery is profound, and I am saying that it refers to Christ and the church. (Ephesians 5:31-32)
If marriage always pointed us to Christ it may be that at the consummation of everything, in the new age, the highest purpose for marriage will have been completed so that it will be "unnecessary" in the new bodies we’ll inhabit in the new heaven and new earth. I don’t know why God established marriage in paradise (in the Garden) but not have it endure into the future paradise except for this reason.
