How do we know that Jesus is God's final revelation?

The New Testament clearly presents Jesus as the final and complete revelation of God. Hebrews 1:1-2 states that God spoke through the prophets in various ways but in these last days has spoken to us by His Son. This underscores that Jesus is the ultimate revelation of God's nature and Will. He declares, 'I am the way, the truth, and the life' (John 14:6), emphasizing that no one comes to the Father except through Him. Therefore, all who seek knowledge of God must look to Christ, as He fulfills all the promises and prophecies of the Old Testament.
