Righteousness is the reason Jesus has come—to make the people righteous through and through. He then begins to interpret the law of Scripture for them with this in mind.
21 As you know, long ago God instructed Moses to tell His people, “Do not murder;[a] those who murder will be judged and punished.” 22 But here is the even harder truth: anyone who is angry with his brother will be judged for his anger. Anyone who taunts his friend, speaks contemptuously toward him, or calls him “Loser” or “Fool” or “Scum,” will have to answer to the high court. And anyone who calls his brother a fool may find himself in the fires of hell.
23 Therefore, if you are bringing an offering to God and you remember that your brother is angry at you or holds a grudge against you, 24 then leave your gift before the altar, go to your brother, repent and forgive one another, be reconciled, and then return to the altar to offer your gift to God.
