The passage regarding judgement day that you referred to can be found in Matthew 24:36):
“But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.”
As a man on earth Christ voluntarily limited His knowledge and power to the capacities of human beings in order that His own perfect life might be an example of how we should live, and that His ministry might be a pattern we could follow, aided by the same divine guidance and help that were His (Luke 2:52).
For this reason Jesus accepted humanity when the race had been weakened by four thousand years of sin. Like every child of Adam He accepted the results of the working of the great law of heredity. He was permitted “to meet life’s peril in common with every human soul, to fight the battle as every child of humanity must fight it, at the risk of failure and eternal loss.
The child Jesus was not supernaturally endowed with wisdom above that of other normal children. He thought, spoke, and acted with the wisdom of a child. But at each stage of His development He was perfect, with the simple, natural grace of a sinless life. The environment in which Jesus grew up—the proverbial wickedness of Nazareth—subjected Him to all the conflicts which we have to meet, yet even in childhood and youth His life was not marred by a single wrong thought or act.
In His humanity, Jesus limited His knowledge that He may be an example for us of how to live depending on God for everything.
