Jesus is called the faithful witness because He perfectly reveals God to humanity and speaks the truth about salvation.
In Revelation 1:5, Jesus is acknowledged as the faithful witness, emphasizing that He is the principal one through whom God communicates His truth. He declared, 'No man knoweth the Father, but the Son,' illustrating that comprehensive knowledge of God comes solely through Christ. As the faithful witness, He not only conveys God's Word but embodies it, affirming in John 14:6 that He is 'the way, the truth, and the life.' His testimony comes from His unique position as the only begotten Son, sent to reveal divine truths about God, man, and redemption, thus confirming His role as the ultimate guide to the Father.
