This question probably arose in the person's heart because of the hard sayings Jesus had be giving to the people. In chapter twelve Jesus had spoken of the cost of being a disciple. The commitment required an act of obedience that could potentially lead to division in some relationships. Some people would not understand why a friend or family member would turn to Jesus, and the act of doing so would lead to hostility and conflict on their part.
To follow Jesus was a call to give one’s whole life into the hands of God, not holding back anything, and knowing some people would not understand. So, in the eyes of someone witnessing it all, to follow Jesus was demanding, so demanding that he thought that maybe there would just be a few people who would dare take up their cross and follow Jesus!
Jesus didn’t directly answer his question. Instead he got the person thinking about the kingdom of God. He spoke of the fact that some people would just never get it but that others from all over the world, “east and west and north and south” would come into the kingdom and “recline at the table in the kingdom of God” (vs. 29).
The question the man asked was too narrow. The kingdom is huge, and the invitation is to all. “whosoever will, let him take of the water of life freely” (Rev. 17b KJV).
“Whosoever.” What a mighty, wonderful, and awesome God we serve.
