JOHN: 62 YEARS AFTER THE CROSS.

The Apostle John was unique of all the Apostles of a Jesus Christ because he was one said to be the closest to Jesus(Jesus assigned John to care for His mother), one of the first to follow Jesus, and one of the youngest of Apostles, and lived the longest--writing the last letters to defend and promote the Christian Faith.

JOHN THE APOSTLE WROTE THE GOSPEL OF JOHN BEFORE THE FALL OF JERUSALEM ABOUT 69AD

John’s gospel’ first chapter begins: 
In the beginning was the Word, and the Word was with God, and the Word was God.

The same was in the beginning with God.

All things were made through him; and without him was not anything made that hath been made.

In him was life; and the life was the light of men.

And the light shineth in the darkness; and the darkness apprehended it not.

There came a man, sent from God, whose name was John.

The same came for witness, that he might bear witness of the light, that all might believe through him.

He was not the light, but [came] that he might bear witness of the light.

There was the true light, [even the light] which lighteth every man, coming into the world.

He was in the world, and the world was made through him, and the world knew him not.

He came unto his own, and they that were his own received him not.

But as many as received him, to them gave he the right to become children of God, [even] to them that believe on his name:

who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.

And the Word became flesh, and dwelt among us (and we beheld his glory, glory as of the only begotten from the Father), full of grace and truth. 

JOHN WROTE HIS GOSPEL ABOUT 95AD AND HIS LETTERS AFTER THE JEWISH-ROMAN WAR BETWEEN 85AD AND 100AD.

John is now an old man, probably in his 90s.  He is also an experienced old man, having lived a hard life of suffering for the Faith and having watched friends, loved ones, family(his brother James) and fellow Apostles put to death for this Faith--most were very cruel deaths.  John would not be promoting the Christian Faith as he does if what he witnessed of Jesus Christ and the Gospel was a lie. So John's life and letters further confirms the truth of the Gospel.  Most of his life had witnessed, more than any man, Gospels of Christ--Christ's 3 years of teaching, Christ's crucifixion, and His resurrection.  Witnessing Christ's Ascension, he also witnessed Pentecost and the ministry of the Holy Spirit.  If the Gospel of Christ was a lie, the Apostle John would certainly know it.  And John's 7 letters to the churches is highly critical of most local churches (repent or be excommunicated), including the one he attends (Ephesus), so John is very open to voicing the truth.

Remember therefore whence thou art fallen, and repent and do the first works; or else I come to thee, and will move thy candlestick out of its place, except thou repent    Revelations 2:5

It is interesting to see  that John’s belief in Jesus Christ hasn  faltered in the slightest since his  last seeing Jesus, but as a matter of fact after over 30 years of “walking in the  shoes of experience he is now sseeing  Jesus in His glorified state, probably as the Apostle Paul saw Jesus on the road to Damascus. 

Revelations 1:13-20

And his head and his hair were white as white wool, [white] as snow; and his eyes were as a flame of fire;

And his head and his hair were white as white wool, [white] as snow; and his eyes were as a flame of fire;

and his feet like unto burnished brass, as if it had been refined in a furnace; and his voice as the voice of many waters.

And he had in his right hand seven stars: and out of his mouth proceeded a sharp two-edged sword: and his countenance was as the sun shineth in his strength.

And when I saw him, I fell at his feet as one dead. And he laid his right hand upon me, saying, Fear not; I am the first and the last,

and the Living one; and I was dead, and behold, I am alive for evermore, and I have the keys of death and of Hades
