The parable of the Good Samaritan serves as a dramatic, practical illustration of the New Covenant Law of Messiah, in which unqualified enemy-love has replaced the ways God Himself sometimes dealt with His enemies and the commands given to Israel under the old covenant. The takeaway becomes even more striking when read alongside the preceding account of Jesus’ rejection by a Samaritan village.

Before telling the parable, a Samaritan village had rejected Jesus because He was traveling toward Jerusalem (Luke 9:51–53). James and John responded by asking permission to call down fire from heaven and destroy its inhabitants, recalling the judgment exercised by the prophet Elijah (2 Kings 1:9–12). Jesus, however, rebukes them (as recorded in later manuscripts of Luke 9:55):

“You do not know what spirit you are of, for the Son of Man did not come to destroy people’s lives, but to save them.”

This reveals a profound theological contrast between the spirit that is now to govern Jesus’ disciples and the earlier prophetic judgments exemplified by Elijah. Under the Old Covenant, God’s holiness and justice could require lethal judgment through His appointed agents. Jesus, however, reveals a different response toward those who reject Him: mercy rather than retaliation, let alone killing the enemy (Luke 6:35–36; 19:10). It is against this background that the parable should be understood and applied to Christian living.

In the parable, a Jewish expert in the Law, quoting Deuteronomy 6:5 and Leviticus 19:18, seeks to justify himself by asking Jesus, “Who is my neighbor?” (Luke 10:25–29). Jesus challenges the lawyer’s restricted understanding of neighbor-love by making a Samaritan—a member of a group religiously and ethnically despised by most Jews—the model of obedience. Jews and Samaritans generally did not associate with one another (John 4:9). His choice is therefore deliberate and stands in perfect harmony with the “new command” (cf. John 13:34–35) that includes blessing those who curse you, praying for your persecutors, and showing mercy without discrimination (Matt. 5:43–48; Luke 6:27–36).

Note, then, how Jesus effectively reverses the lawyer’s question from “Which people qualify as my neighbors?” to “Which of these three proved to be a neighbor?” (Luke 10:36). The lawyer answers, “The one who showed mercy” (v. 37).

Jesus then concludes with a clear, unambiguous, and unqualified command:

“Go and do the same” (v. 37)—that is, whether toward your loved one, neighbor, or enemy.

Thus, the Good Samaritan is the practical counterpart to Matthew 5:44 and Luke 6:27–36. Jesus did not merely command His followers to expand their ethnic circle of loving family or neighbors; He challenged the very boundaries separating neighbor from enemy, and ultimately Jew from Gentile. The person whom Messiah commands us to love may be our own enemy or someone entirely outside Israel’s covenant community. This is one of the defining hallmarks of the New Covenant Law of Messiah (1 Cor. 9:21; Gal. 6:2; Rom. 13:8–10), in which unqualified enemy-love is to govern the people of God. More importantly, it clearly shows that Jesus was not merely sent to repeat Moses but to “fulfill” the Old Covenant Law and all the Prophets to their intended goal and purpose (Matt. 5:17; Rom. 10:4).

Paul later explains that Messiah is “the end of the Law for righteousness to everyone who believes” (Rom. 10:4). Therefore Hebrews 10:1 calls the Law as a whole a single “shadow of the good things to come,” meaning it is not the ultimate reality.

The parable serves as a clear contrast of one of the most vital differences between the old covenant Law of Moses and the Law of Messiah. James and John wanted to call down fire upon the Samaritans; Jesus made a Samaritan the example of the very mercy His disciples must practice. Under the Law of Messiah, the enemy is no longer someone to be excluded from our love, but someone we are expressly commanded to love.

This is not merely a change in whom we call our neighbor. It is a radical transformation in how the people of God are commanded to treat their enemies (Matt. 5:44–45; Luke 6:35–36).
