No-one has seen God but God the one and only, who is at the Father's side, has made him known.
I and my Father are one, says Jesus later in this Gospel. How silly that some people assume that God cannot be known. Among the many reasons that we have Jesus in Scripture is to make God Known. Only Jesus has this information. If you want to know God, study Jesus. From him we know that God is love, long suffering, kind - with a special affection for children, but also witty, imaginative, creative, good with people, wise, and though sometimes angry, always compassionate, powerful, valient for the truth and a hater of evil; concerned for his friends while not being blind to their faults, capable, confident, charismatic; giving gifts to those who don't deserve it out of mercy and grace.
So ends the prologue to John's Gospel. This is the poem that I wrote as a summary:
But Jesus was not Jesus then, no more
The Virgin Mary’s son; He was the Word,
With God, the three in one, in rapt rapport
Held fast by love. The Holy Three conferred
And made the sky, the earth, the sea; His hand
In each creative act. The Spirit soared
Above the seas before that great command,
“Let there be light!” He was the Light; adored
By angels. Darkness could not comprehend.
Then there was life, of countless, teeming kind.
In Him was life and His that life to lend;
The light of men; for Man he had designed
To hold His image and when thus constrained
To free from bondage those whom sin had stained.
