All That He Saw -Rev 1:2

Revelation 1:2 who testified to the word of God and to the testimony of Jesus Christ, even to all that he saw.

The mature Christian bears more witness to his or her Father than self.  The less mature a Christian is found, the less they reflect God.  A person cannot long  reflect something they are not, just as they cannot share something they don’t have.

  From the Greek:

μαρτυρέω martureō ; from 3144 ; to bear witness, testify:-- add...testimony(1), attested(1), bear...witness(1), bear   -NASB Strong’s Dictionary

In the gospel of John, Jesus is called the word of God.  The testimony of Jesus is from God, He Himself saying He only spoke the words given to Him by the Father. Just as a word that passes our lips begins before it is spoken, in the beginning He was with God.  The two phrases describe the same thing.  Jesus is the word of God, and as John tells us is God.

John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.

So the testimony of Jesus Christ is the word of God, the Son and the Father are one.  The truth of this is confirmed by the one Spirit.  We have been given the revelation of God both in the coming of Jesus and the Holy Spirit.  John had the privilege of seeing and being with Jesus while He was here on earth.  He had listened to the word of God given voice by the one sent from God, touched the incarnation of the Son and Savior,  and beheld the crucifixion, death, and resurrection of our Lord.

Like John the Baptist preparing the way for Jesus, a voice crying out in the desert wilderness, John gives witness to the second coming of Jesus, a voice in the wilderness of the world which is dry from the lack of knowledge and wisdom, the things of God.  In this book, John shares “all that he saw”.  His experience of Christ is unique, as it is for all of us, but John was chosen for a particular purpose and gifted to that end.
