The book of Revelation is an eschatological and prophetic book probably written by the disciple John.
Jesus Christ, referring to himself, in the book of Revelation, makes the following statement: "I am the alpha and the omega, the beginning and the end" Revelation 1: 8.
Christ personifies eternity, remember that eternity is the simultaneous possession of all time, past, present and future.It is from this affirmation that Christ is uncreated and coexistent with the Father and the Holy Spirit (Holy Trinity). God exists, in a theological sense, out of all notion of time, we can only apply concepts of time to finite and created creatures.
There are other similar affirmations in the Gospels: "I am the door" John 10: 9, in reference to wisdom;"I am the light", John 12:46, in reference to the truth; "I am the bread of life", John 6:34, in reference to the spiritual food.
God is the origin of the perfections that we observe in the creation and it is God's desire to radiate his perfections to the creatures. The gifts are perfections. Jesus personifies the perfections of God, his "gifts" and "divine attributes".
Jesus also defines himself as "son of man": Matthew 8:20, Matthew 20-.28, Acts 7:56, John 12-.34. The concept of "son of man", we see in the book of Daniel (old testament), like Jesus, he is also "son of man".
Then we can say that the kingdom of God has a double meaning. The man makes himself “son of God” that is to say the man lives the gifts of God, and on the other side “God became son of man” that is to say the spiritual gifts and perfections of God are personified in Christ.
The affirmation in the gospel of Christ as "son of man" synthesizes the idea of the divinity of Jesus and closes the teachings of the Sermon on the Mountain, Jesus personifies in himself the Beatitudes, he is the "blessed" by excellence.
