Question from a reader:
Q) If Jesus is God, and the same as The Father, how could he not know when He will return?
A) This is a great question.
This refers to a statement Jesus made in the gospel of Matthew. In this conversation, Jesus is talking about when the end times are going to come.
He says in Matthew 24:36,
But concerning that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only.
Clearly Jesus is saying that only God the Father knows when this time will come. But if Jesus is one with God, and is every bit as God as The Father is, then how could the Father know something that Jesus does not?
When God became a person, he had to lay down some of His Godly attributes, or He would really not have been a person. This does not mean that Jesus was less divine. It means that He surrendered some of His Godly power and qualities so that he could be fully human.
After all, it is not very human to be able to know everything, be everywhere, and have unlimited power. For God to become a human, those qualities had to be surrendered, or Jesus was not a human.
When God became a human named Jesus, it was not that God became lessor, by subtracting from the Trinity. Rather, God became greater, by adding humanity to the Trinity.
Without Jesus, the Trinity had no humanity in it, and therefore God was inaccessible to people, and unrelatable. When God added humanity to himself through the life of Jesus Christ, He became somehow even greater. Saying it that way makes it sound like there was a time when He was lessor, but in reality, God always had Jesus as He is now, within the Trinity, from before time, as we know from the Gospel of John Chapter 1.
So, to summarize, Jesus surrendered access to the all knowing powers of the God-Head in order to become fully human, while still remaining fully divine.
