Welcome to Christian Chat denny1953. The Father is not hiding anything from His only begotten Son. The Son, who is God in flesh, (John 1:14) became a man.
It's explained at Philippians 2:5-8. "Have this attitude in yourselves which was also in Christ Jesus, vs6, who, although He existed as God (or in the form of God) did not regard equality with God a thing to be grasped. vs7, but emptied Himself, taking the form of bond-servant/human being and being made in the likeness of men. vs8, And being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross."
What this means is that instead of clinging to what was rightfully His, (because He was God) He emptied himself. What did He empty Himself of? He "DID NOT" empty Himself of His divine nature. He "DID NOT" cease to be deity for a short period of time. In other words, God cannot cease to be God. Nor did He divest Himself of His attributes.
He divested Himself of the prerogatives that belonged to Him. In other words, He emptied Himself of the "EXPRESSION" of deity, not the "POSSESSION" OF DEITY. It's also important to note that His emptying was voluntary. He had to do this in order to take upon Himself the essential attributes of a servant/human being. And as a human being of course He would not the day or hour of His own return. Does that make sense?
IN GOD THE SON,
