How do we know that Jesus spoke the truth?

Jesus' declarations are grounded in His divine nature. As God's incarnate Word, everything Jesus uttered was true and meant to convey the realities of God's kingdom and moral expectations. In Matthew 23, His proclamations, including 'woe unto you' for the Pharisees, were not mere criticisms but declarations rooted in a holy Righteousness. His authority, as affirmed by His miracles and teachings, holds up the truth of His words, making it imperative for believers to acknowledge and respond to what Jesus teaches about sin, redemption, and salvation.
