In today's Gospel, Jesus is asked a very logical question by the Sadducees about the afterlife; If a woman has several husbands in this life whose husband shall she be in the next.
What Jesus points out is that we have no concept of either the afterlife nor the power of God. And yet he does not tell us the answer. Jesus has come down from heaven so he knows the answer. Why does he do this? Because in this life we are expected to live a life of faith, waiting for these things to be shown to us in the next life. Our problem, and the problem of the modern world, is that we do not want to wait!
