How do we know that Jesus' teachings are authoritative?

The authority of Jesus' teachings is evident in the reactions of His listeners, who were astonished at His doctrine (Matthew 7:28-29). Unlike the scribes who quoted others and relied on tradition, Jesus spoke with the authority of God Himself. He proclaimed truths directly and personally, establishing Himself as the ultimate interpreter of God's will. His miraculous works, fulfillment of prophecy, and divine declaration of radical truths confirm His authority. Each teaching aimed to challenge the prevailing understanding of righteousness and reveal deeper spiritual truths related to God’s kingdom.
