"Let the dead bury their dead"

He would like to wait until his father dies and conduct his own affairs for as long as is necessary for everything to be concluded in peace, brought to an end, and handed over in good order to someone else.  After this he wants to come to Jesus.  But who knows when that will be?  Will he still then be able to rise up and follow Jesus? 

What is made clear to us here is that assent to Jesus' summons has priority and demands totality.  That means it takes precedence and demands the totality of our being.  One cannot simply offer a piece of oneself, a portion of one's time and one's will.  In that case one has not answered this summons that is so great that it really demands and fills a whole life, but only fills it if it is offered totally.

This also means that there is a moment of Jesus Christ which one cannot put off and calculate and say: "Yes, I want to all right, but at the moment it is still too risky for me.  At the moment I still want to do this and that." 

One can miss the moment of one's life, and with prudence gamble away the real worth of one's life never again to be able to recover it.  There is the time of being called in which the decision is present, and it is more important than what we have thought out for ourselves and what is in itself quite reasonable.  The reason of Jesus and his summons have precedence: they come first.  This courage to defer what seems so reasonable to us in favor of the greater thing that he is, is decisive not only in the first moment but continually on all parts of the way.  It is only in this way that we really come close to him.
