Some unrelated observations:
- It is more important to be reconciled to your brother than it is to go to worship. (Matthew 5:23-24).
- The heart-level standard for adultery is desire. If I desire someone I am not married to, so that they meet a need, real or imagined, in my heart I am crossing the line. If I am looking or thinking in such a way that it will be about me, then I am committing adultery. God made marriage for the satisfaction of my needs and desires. My contemplation of someone else in connection with those desires is sin.
- It is hard to believe the rabbis taught that it was fine to hate your enemies (Matthew 8:43-44), but Jesus elevated that teaching by requiring love even for those we consider enemies. We are to love those we don't like.
- If the law was not a high enough standard, Jesus wants us to be perfect, like our Father in heaven is perfect.
- God's perfection is seen here in the context of loving enemies!
