How do we know that Jesus is the true teacher from God?

Nicodemus acknowledges Jesus as a teacher come from God, stating that no one could perform the miracles He did unless God was with him (John 3:2). Jesus’ miraculous works serve as divine confirmation of His identity and teaching. Unlike any other, He speaks with authority and reveals the character of God, demonstrating that He is not merely a man with knowledge, but the incarnate Word of God who imparts true spiritual wisdom. This solidifies the belief that Jesus is indeed the ultimate Teacher sent from the Father to reveal the truth and how God saves sinners.
