It is for this reason that God's heritage has been untransmittable through the descendants of Adam and Eve. The goal of resurrection is to attain the very aforementioned Tree of Life. In that the Tree of Life is the prerequisite for true marriage, then the resurrection process will only take place on the individual level. Therefore, no marriage will be true until the completion of the process of resurrection and the reclamation of the right to eat of the Tree of Life. The scriptures indicate no marriage in Heaven.
Resurrection takes place on the individual level.
The Tree of Life is a symbol of perfection which was the prerequisite for original marriage. Before the completion of the resurrection process, no true marriage exists or can exist and therefore we see the response that Jesus gave in Matt. Jesus was single, Paul said we could be a eunuch for the Gospel's sake. In the beginning, God established the ideal marriage He created Adam and Eve and told them to be fruitful, multiply and have dominion. As a result, their multiplication only brought forth children of sin and not children of God.
