How do we know that Jesus speaks for God?

The assurance that Jesus speaks for God can be found throughout the Gospels, particularly in His words from John 14:10-11. He asserts that His unity with the Father validates both His teachings and actions, as all the fullness of the deity dwells in Him (Colossians 2:9). Jesus invites His followers to believe in His words by referencing the miraculous works He performs, which serve as confirmation of His divine authority. The Gospel accounts consistently illustrate how Jesus uniquely fulfills the prophetic scriptures and embodies God's redemptive plan for humanity, cementing His role as the ultimate revelation of God’s truth.
