"And Jesus looking upon him loved him, and said unto him, One thing thou lackest: go, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, follow me."
What Jesus tells that man when he asks "What must I do to inherit eternal life?" is not what we would answer to someone asking the question of us. Most of us would say, pray to ask Jesus into your heart, read the Bible every day, go to church, fellowship, worship, and so on.
Does that mean we think Jesus was not really serious with his answer? Jesus says absolutely none of those things we would expect. If we do not take Jesus seriously, should we expect Jesus to take our faith seriously? This isn't a specific command for one person in particular, and when taken as the answer to the question "What must I do to inherit Eternal life?", this answer seems rather important to salvation.
Jesus gives a rather practical answer. The faith he is asking this man to show is not personal saving faith but rather interpersonal saving faith that touches the heart of social concern. What Jesus is asking for is a radical trust in him and not in possessions. So no matter how much technology we can cram into our churches, we could do more for not only the world's salvation but ours as well if we only sold it to the poor and followed Him.
