Speaking the Truth

The sermon begins by emphasizing the importance of speech as the primary means of communication between people. Through words, we express our desires, thoughts, dreams, share information, and reveal our feelings. The pastor cites Goethe's quote about the rarity of truly right and honest words. Speech can bring comfort or cause harm; it can teach or reveal hatred. The pastor illustrates with President Roosevelt's call to "speak the truth, the whole truth, frankly and boldly" during the Great Depression, which brought confidence to the people through words of courage.

The pastor explains that Jesus Christ in this Scripture passage does not forbid believers from making oaths, but teaches them to speak truthfully without deception or fraud. People swear for two reasons: to prove the credibility of their words and to have a higher authority as a witness. Both the Old and New Testaments teach about oaths, from Moses, Jeremiah, and Paul. The Old Testament teaches two important things: not to treat oaths lightly (Exodus 20:7, Leviticus 19:12) and that once you make a vow, you must keep it (Deuteronomy 23:21, Ecclesiastes 5:4-5). God Himself makes oaths with Noah and Abraham, demonstrating the value of oaths. The pastor points out that the Pharisees distorted this teaching by focusing on the formula of swearing rather than the substance of truthfulness. They created detailed rules about acceptable and unacceptable ways of swearing, such as distinguishing between swearing by the gold of the temple versus swearing by the temple itself. Jesus exposes this absurdity by reminding people that God hears all oaths, whether swearing by heaven, earth, the city, or one's own body, because God is the Creator of all things. The pastor notes two common errors: swearing carelessly and swearing falsely.

The pastor teaches that on the Day of Judgment, Christ will judge us not only by faith and deeds, but also by our words (Matthew 12:36-37). Speech reflects the true nature of the heart: "out of the abundance of the heart the mouth speaks" (Matthew 12:33-35, Luke 6:45). A good person produces good things because the heart is full of goodness; an evil person produces evil things because the heart is full of evil. Evil speech can harm others, while wise speech benefits the listener. Proverbs teaches that a deceitful tongue and flattering mouth bring ruin (26:28), and God hates false witnesses and those who sow discord (6:16-19). The pastor emphasizes that the tongue, though small, is extremely harmful and no one can completely control it (James 3:6-8). One of the most damaging things in the church is gossip—when a confidence becomes a story about another person, and that story changes as it passes from person to person, creating misunderstandings and prejudices. The pastor advises that when hearing someone speak about another, one should ask to write down the words and have them repeated, or refuse to listen if the speaker is unwilling for their words to be repeated or their identity revealed. Paul warns about evil things like jealousy, anger, discord, gossip in the church (2 Corinthians 12:20). Christ's teaching on church discipline (Matthew 18:15-17) emphasizes addressing the person privately first, then inviting witnesses, and only then reporting to the church. The conclusion: believers must follow the teaching "yes, yes; no, no," because adding or subtracting anything comes from evil (Matthew 5:37).
