When Jesus was baptised and the voice came down from Heaven "This is my son in whom I am well pleased." In the book of Mark (9:7) when Moses and Elijah met with Jesus and God's voice came down, "This is my beloved Son; hear Him." There are other accounts of this instance in Matthew and by Luke.

When Peter said "Thou art the Christ," and Jesus answered that "flesh and blood hath not revealed this unto you, but my Father."

In the scripture where Jesus says even He doesn't know when the end of the world will be...that only God knows.

When Jesus promised that "In my Father's house are many mansions, and I go to prepare a place for you."

In the prayers He made when the time of His death drew near, as He asked, "Father if you will, take this from me."

In the verse "For God so loved the world that He gave His only begotten son, that whosoever believeth in Him should not perish, but have everlasting life."

On the cross when He cried out, "My God, My God, why hast thou forsaken me."

The many times when Jesus speaks of "sitting at the right hand of God."

And yet He explains that all Christians are one, even as we (God and Jesus) are one. And in the same context, in explaining how a man and wife become one.

I like to compare it to an egg...how one egg can be separated into shell, yolk and white, three in one, as are the Father, The Son and the Holy Ghost.

But don't argue among yourselves if you still don't understand. The common ground of all Christians is to be saved by the blood of Christ. He'll explain the rest when we're in Heaven with Him.
