What does the Bible say about the role of Christ as a witness?

Christ is referred to as the ultimate witness in Scripture, where He reveals the holiness and righteousness of God. In Isaiah 55:4, it states that God gave Him for a witness to the people, indicating that all of God's messages and declarations to humanity come through Christ. This is further supported by John 1:14-18, where it emphasizes that the Word, Christ, was made flesh and reveals God to us. He is essential in helping us understand God’s nature and His plan of salvation, affirming His role as our mediator and the one who bears witness in our hearts.
