If we read today's gospel on a purely human level it appears that Jesus is giving dire warnings of being ready for death. However, lets look at it another way: Jesus has gone to the wedding feast. He comes to us in so many ways; in others, in things we see need to be done.
So blessed are we when Jesus comes back from the wedding feast and finds us ready to do his work. If we are ready to open the door to our heart he shall come in and wait on us, that is give us all the spiritual help we need.
All Jesus asks us to do is to be ready and willing to help when he comes. Not mush to ask, is it.
