Jesus is the Good Samaritan described in His parable. While we're still trapped, wounded and half-dead in sin, He came and picked us up. With His sacraments He continues to heal and strengthen us, and guide us into His everlasting kingdom. When He said: “Go and do likewise,” he is telling us to follow Him, to reach out to our neighbors in need, with compassion and without reservation.
At the time of Jesus' teaching, Samaritans had nothing to do with Jews, and some even despised one another. Yet the Samaritan that Jesus described not only stopped for the victim who came down from Jerusalem, he also treated his wounds and brought him to an inn to care for him out of compassion.
This is not only risky, time-consuming, and can also cost a lot of money. The injured person can be a robber in disguise, so approaching him can be dangerous. The Samaritan may be in a hurry, so stopping for the stranger to take care of his wounds and then carrying him to an inn, not only delayed his trip, but can very well interrupt his original itinerary. Lastly, he told the innkeeper, “Take care of him. If you spend more than what I have given you, I shall repay you on my way back.” How does he know he can afford what the innkeeper will charge him?
When we care for people around us, we usually first assess if we have the time, money and ability to do so. It also depends on who that person is that we're helping. However, Jesus teaches us to look at the needs of our neighbor first, even if that neighbor is a stranger, and that is truly, love our neighbor as ourselves.
“Go, and do likewise.”
