How do we know Jesus' teachings are true?

We know Jesus' teachings are true because He declares that His doctrine is not His own, but from the Father who sent Him (John 7:16). His authority sets Him apart from the scribes, who cannot claim the same. Jesus illustrates the truth through parables and direct teachings, addressing matters of eternal consequence. The transformation in the lives of those who hear and respond to His message is also a testament to its truth. Ultimately, the truth of His teachings is affirmed by His resurrection and the fulfillment of prophecy, as He embodies the reality of His words.
