Today, God's word deals with the outstanding matter of the resurrection from the dead. It is peculiar that, as the Sadducees did, we keep on asking useless and pointless questions. We try to explain the substance of afterlife with world criteria, when in the world to come everything is different: «But for those who are considered worthy of the world to come and of resurrection from the dead, there is no more marriage» (Lk 20:35). Setting off from wrong criteria leads you to wrong conclusions.
Should we love each other more and better, we would not be surprised to see that, in Heaven, there is not the exclusive kind of love we have down here, otherwise normal for us because of our limited intelligence, but which makes it very difficult for us to get away from our closer circles. In Heaven we shall all love each other with a pure heart, without any feelings of envy or distrust, and, not only husband and wife, our sons or those or our own blood, but everybody, without exception nor language country, race or culture discriminations, for «true love attains a great strength» (St. Paulinus of Nola).
These words of the Scripture coming out of Jesus' lips are very convenient for us. They indeed are, for, it could happen to us that, in the maelstrom of our daily chores that do not allow us any time to think, and influenced by an environmental culture that denies eternal life, we should be doubtful with regards to the resurrection of the dead. Yes, it is very convenient that the same Lord tells us there will be a future beyond the destruction of our body and of this passing world: «Yes, the dead will be raised, and even Moses implied it in the passage about the burning bush, where he calls the Lord the God of Abraham, the God of Isaac and the God of Jacob. For He is God of the living and not of the dead, and for him all are alive» (Lk 20:37-38).
