Revelation 1:5 And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,

The message that the Apostle John sends to the churches is from God the Father, God the Holy Spirit, and God the Son, Jesus Christ. The Son is called the faithful witness. A witness is one who witness to ascertainable facts. Jesus Christ is the final revelation of God to mankind. Who is Jesus Christ? Jesus Christ is God.

His Deity is well attested by the writer of Hebrews, who gave a most complete description of Jesus Christ’s Person and work when he said in Hebrews 1:1-4 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, 2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds; 3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high; 4 Being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they.
