In this chapter, Jesus teaches us not to judge / condemn another person—no judgmentalism. He encourages kingdom citizens to ask, seek and knock. He teaches the Golden Rule. He tells his listeners to travel the restrictive path and enter through the narrow gate. He says to be fruit inspectors, because false prophets are coming. He announces that some will claim him to be Lord and do charismatic gifts, but he will tell them to depart from him, for he never knew them. He talks about two houses, one built on a strong foundation, and another built on sand.
In this chapter, these topics are introduced: Giving to the needy without display; the Lord’s Model Prayer; fasting with the right attitude; laying up treasures in heaven; our light must shine. We cannot serve God and Mammon. We must not be anxious about the basics but seek God’s kingdom first.
The first chapter in the Sermon on the Mount; the Beatitudes; we are salt and light. Christ came to fulfill the law. Avoid anger; avoid lust; divorce should be rare and only for one exception. Don’t swear oaths. Don’t follow ‘eye for an eye,’ but live a surrendered life. Love your enemies. Through most of those passages, Jesus presents his six antitheses: “You have heard it said … but I say to you.”
