And behold, a lawyer stood up to put him to the test, saying, "Teacher, what shall I do to inherit eternal life?" He said to him, "What is written in the Law? How do you read it?" And he answered, "You shall love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind, and your neighbor as yourself." And he said to him, "You have answered correctly; do this, and you will live."Think about that: for Jesus, it was enough to say that loving God greatly (with all your heart and with all your soul and with all your strength and with all your mind) and loving men particularly (that is, the same way you love yourself) to warrant the inheritance of eternal life. There’s no mention there of resurrection or repentance, is there? Yet Christ says, “You have answered correctly; do this and you will live.”
Was Jesus preaching “sloppy agape”? Where’s the Glory of God? Where’s the law, and man’s inability? Doesn't this conversation intimate a synergistic view? How could the lawyer who was testing Him be “correct” to say that the Law demands love -- in the right way, and two different kinds of love to be sure – and that this is enough to gain eternal life?
Now, think on this: the matter of loving God as it is manifest in loving people is what is at stake here. The lawyer asked the question “who is my neighbor” to “justify” himself – that is, either to demonstrate that his first question was not a trap, or to demonstrate that he is not himself a fool for asking a ridiculously simple question.
So the matter of “who is my neighbor” is about how we keep the commandment to love God and love our neighbor. And in that, Christ [as Luke tells it] gives us 3 examples of men who have some relationship with God and with an actual person.
You've heard this sermon before, I am sure: the priest avoided the man; the Levite avoided the man. But the Samaritan did not avoid the man. It seems like a kindergarten Sunday school lesson, I am sure, but let’s think about this for a minute. In John 4, the woman [a Samaritan] at the well said to him, "How is it that you, a Jew, ask for a drink from me, a woman of Samaria?" (For Jews have no dealings with Samaritans, John makes clear) That is, the Samaritans worship God apart from the Jews, and the Jews think that because of this, there is enmity between them – the Samaritans are rather less than lovers of God.
But it is the Samaritan who, as Jesus says, “proved to be a neighbor”.
Consider it: the Levite and the priest have the temple, and its sacrifices – but what do those things cause them to do? The Lawyer can cite the Sh’ma, and connect the admonition of the Sh’ma to obey God and His law to the broad command of Lev 19 which says, frankly, that you shall love your neighbor as yourself in a concrete way. Don’t lie; don’t steal; don’t cheat; care for the poor from your own portion; do not take vengeance, and do not do injustice in court. But Christ tells him that loving God requires you to love people. You can't be doing the former unless you are doing the latter.
See: God is glorified when we love. That may seem somewhat uncontroversial to some people, but there’s a reason God is glorified when we love: it is because God loves. The fact – the indisputable fact of the Bible – is that God loves men, and that love is glorifying to God.
