Marriage and the Kingdom of God

Will there be marriage in the resurrection Kingdom of God? Will people who are married (or were married) here on earth be married in heaven? The answer to this is a resounding 'no.'
When asked by the Sadducees (who did not believe in the resurrection of the dead), "'If a man dies having no children, his brother as next of kin shall marry his wife and raise up children for his brother.' Now there were seven brotehrs with us; and the first married and died, and having no children left his wife to his brother; so also the second, and the third, down to the seventh. Last of all, the woman died. In the resurrection, therefore, whose wife of the seven will she be? For they all had married her" (Matthew 22:23-28).
While the direct question is not whether there is marriage in heaven, Jesus answers that question. "In the resurrection they neither marry nor are given in marriage, but are like angels in heaven" (Matthew 22:30). While at least gender will, I'd imagine, still exist in heaven, we will be without mates, as the angels are. For those of you who are married (perhaps myself one day), you will not be married to one another in heaven. Think about it, if one of you were to die and the other to remarry, who would be married to whom in heaven? Jesus answers that by saying there is not that state in heaven. We will have perfect communion with one another in the resurrected state--it will be far greater than the communion between married couples today. Though you will probably remember that such and such was your wife/husband, you will not have a special relationship together. Rememberyour vows, it is until death parts you. The only reason we would desire to be married in heaven is because we misunderstand and fail to comprehend just how much greater the communion will be in heaven in our resurrected state with all the saints.
In our resurrected state, we will be like Christ (1 John 3:2). Christ is the last Adam. He was unmarried, and we are created in Him, as we were created in Adam. We will be like Christ in this regard (though Christ is married to the Church, His Bride--thus making us married to Christ, as members of His Bride).
So why marriage here on earth? Well, because it is not good for man to be alone (Genesis 2:18). Men need helpers in this life--women. Only those who are celebate really don't need a personal helper; and yet they still need both female and male companionship. Adam existed in what must have been a less perfect state than we shall be in our resurrected state (for we will reflect Christ, not Adam).
Marriage was given because God had ordained (not caused) the fall. Marriage was given as a mysterious symbol of what was to come--Christ and the Church; which marriage reflects (Ephesians 5:31-32). Marriage is a witness to unbelievers (and to believers as well) of Christ's love and relationship with the Church. It is evangelistic and edificatory. That is why God created the marriage bond. Let no one separate it, for Christ and the Church cannot be separated. To separate a married couple is to go against God's divine purpose and witness.
Marriage is a this-life thing. Though do not fail to see that it is extremely good. Humans are sexual creatures, and I'd imagine in some way (I will not conjecture for it would be foolish as to how) we will continue to be in our resurrected state. Praise be to God!
