22. The conclusion of Jesus' conversation with the rich young man is very poignant: "When the young man heard this, he went away sorrowful, for he had many possessions" (Mt 19:22). Not only the rich man but the disciples themselves are taken aback by Jesus' call to discipleship, the demands of which transcend human aspirations and abilities: "When the disciples heard this, they were greatly astounded and said, "Then who can be saved?' " (Mt 19:25). But the Master refers them to God's power: "With men this is impossible, but with God all things are possible" (Mt 19:26).
25. Jesus' conversation with the rich young man continues, in a sense, in every period of history, including our own. The question: "Teacher, what good must I do to have eternal life?" arises in the heart of every individual, and it is Christ alone who is capable of giving the full and definitive answer. The Teacher who expounds God's commandments, who invites others to follow him and gives the grace for a new life, is always present and at work in our midst, as he himself promised: "Lo, I am with you always, to the close of the age" (Mt 28:20). Christ's relevance for people of all times is shown forth in his body, which is the Church. For this reason the Lord promised his disciples the Holy Spirit, who would "bring to their remembrance" and teach them to understand his commandments (cf. Jn 14:26), and who would be the principle and constant source of a new life in the world (cf. Jn 3:5-8; Rom 8:1-13).
