Matthew 8:22 But Jesus said unto him, Follow me; and let the dead bury their dead.
Luke 9:60 Jesus said unto him, Let the dead bury their dead: but go thou and preach the kingdom of God.
Jesus wants to be more important than anything to everyone. People seem to have all sorts of excuses as to why they cannot accept the calling of God at that particular time. They put it off.
Jesus states here, Now is the call of appointment and you must not miss it for any reason.
This is one aspect of many concerning this deep saying of jesus.
