Yeah, it's hard to know, but worth looking into that's for sure. It was when I read that one particular verse about his telling the disciples "all things" the Father told Him that it dawned on me that
no man was supposed to know. I'm sure His perfect faith was fine with not knowing...if that was indeed the case.
John 15:15
Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.
Matthew 24:36
But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
So, He willingly took on all the constraints that would be required of Him being a man, wouldn't you say?
