John 1:1: In the beginning was the Word, and the Word was with God, and the Word was God.
Jesus Christ did not merely give us the revelation of God, but He Himself is the revelation of God:
Colossians 1:19: For in Him all the fullness of God was pleased to dwell . . .
Other prophets often express their unworthiness (like Moses and Isaiah), but Jesus Christ Himself is the worthy one:
Revelation 5:9: Worthy are You to take the scroll and to open its seals, for You were slain, and by Your blood You ransomed people for God from every tribe and language and people and nation . . .
Rather than saying "thus saith the Lord," Jesus Christ speaks with His own authority:
Matthew 5:21-22: You have heard that it was said to those of old, "You shall not murder; and whoever murders will be liable to judgment." But I say to you . . .
A greater than Moses and Elijah is found in Jesus Christ:
Hebrews 3:3: For Jesus has been counted worthy of more glory than Moses - as much more glory as the builder of a house has more honor than the house itself.
Matthew 17:4-5, 8: And Peter said to Jesus, "Lord, it is good that we are here. If you wish, I will make three tents here, one for you and one for Moses and one for Elijah." He was still speaking when, behold, a bright cloud overshadowed them, and a voice from the cloud said, "This is my beloved Son, with whom I am well pleased; listen to him." . . . And when they lifted up their eyes, they saw no one but Jesus only.
Jesus Christ did more than merely give commands; He is the One Who fulfilled all of them perfectly!
Matthew 5:17: Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
Christ is all!
