In Matthew 5:21-26 of His "Sermon on the Mount," Christ drew a strong contrast between His teaching on certain key matters of life and the teaching that had been presented to the Jewish people by their leaders for centuries - teaching from the Old Testament that they had both altered and expanded upon so that it was not anything similar to God's original meaning.  In each of the six subjects of this section, "Reinterpretations of the Law" (murder, adultery, divorce, oath-making, retaliation, and love), He stressed HEART-righteousness.   Learn what the Lord had to say about the sin of murder!  It goes a whole lot further than the actual killing of another person.  In fact, every one of us is guilty of "murder" the way the Lord defines it!   The Lord also laid down some very specific steps for reconciliation with a Christian brother or sister in this section of His Sermon.
