The rich young ruler came to Jesus to ask what he could do to be assured of eternal life, yet all that is required is the man’s whole heart and life.

17 As [Jesus] was setting out on his journey, a man ran up and knelt before him and asked him, “Good Teacher, what must I do to inherit eternal life?”
18And Jesus said to him, “Why do you call me good? No one is good except God alone. 19You know the commandments: ‘Do not murder, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor your father and mother.’” 20And he said to him, “Teacher, all these I have kept from my youth.” 21And Jesus, looking at him, loved him, and said to him, “You lack one thing: go, sell all that you have and give to the poor, and you will have treasure in heaven; and come, follow me.” 22Disheartened by the saying, he went away sorrowful, for he had great possessions.
