Power of the Word
Pastor Tan Thai · Oct 1, 2023
This sermon uses Matthew 5:33–37 and 7:1–5 to teach that Christian speech must be both truthful and loving. Words possess tremendous power—they can wound or heal—and there are no levels of truthfulness for believers in the kingdom of God. True transformation comes from remembering one's sinful condition and God's grace, which empowers honest and edifying speech.
The sermon begins by recalling the Sermon on the Mount as a message about the kingdom of God where Christ has authority over believers' lives. Becoming Christian is not moral self-improvement but renouncing self-mastery and obeying Christ. When believers surrender power, Christ's supernatural power floods into their lives—transforming them progressively into His likeness. The Gospel is not people trying to be good; it is internal transformation by the Holy Spirit that results in kingdom righteousness exceeding the legalistic morality of the Pharisees.
The second section establishes the power of words from Proverbs and biblical teaching. Words are devastating or healing—"Reckless words pierce like a sword, but the tongue of the wise brings healing." The speaker explains that words deeply affect both hearers and speakers, since when we think something and clothe it in words, it impacts our own minds. Words are "little bombs" with power to wound or heal souls. Therefore, all biblical teaching about speech boils down to two principles: truth and love. Truth without love is coldness and self-righteousness; love without truth is cowardice and self-indulgence. Both must go together.
The third section develops detailed doctrine on truth through Matthew 5:33–37 on oaths. Christ forbids different levels of truthfulness—do not swear by heaven, earth, Jerusalem, or your head, for all belong to God. Every "yes" and "no" a Christian speaks is an oath before God's presence. The speaker applies this to modern society where there is a distinction between public and private records, yet Christ demands complete integrity across all spheres—public and private, general and specific. The spirit of judging is shown through how one accepts criticism: some dismiss criticism because they would lose face, failing to live out kingdom righteousness.
The fourth section presents doctrine on love through Matthew 7:1–5 on judging. Christ does not forbid evaluating wrongness—He warns against false prophets and condemns abuse of ordinances. Rather, He warns against the Pharisaic spirit of judgment wherein instead of assessing a position, one dismisses and condemns a person. Judging means sentencing someone out of one's life; it manifests most clearly through gossip, since the motive is not to help or address sin but to feel superior and dismissive. Only God has authority to judge persons; believers must address positions while maintaining mercy toward people.
The final section applies the message to real life. Christ teaches that "out of the abundance of the heart the mouth speaks"—therefore no New Year's resolution or willpower can change speech without a transformed heart. To speak truthfully and lovingly, believers must (1) admit the truth about themselves as helpless sinners, and (2) receive God's verdict that they are accepted and righteous in Christ. Humility born from kingdom righteousness is the absolute prerequisite for beautiful, truthful, and loving words. To the degree one remembers the bad news about oneself and the good news in Christ, to that degree one's words become beautiful and healing things.
