“But of that day and hour no one knows, not even the angels in heaven, nor the Son, but only the Father.” Mark 13:32.
When Jesus spoke these words, the Father had not revealed to Jesus the time of his return. But this does not mean that Jesus would never know.
Because the scriptures do not tell us why the Father did not reveal this to His Son, we can only speculate. Speculation without a scriptural “thus saith the Lord” can lead to false conclusions and errors in doctrine. Therefore, we must be content knowing that at the time Jesus was asked about his second coming, it was only for the Father to know.
However, this event does prove that, although Jesus and the Father are one in purpose, they are not the same in knowledge. It shows that the Father has knowledge that the Son does not have. This is in harmony with the scriptures that the words that Jesus spoke were given to him by the Father. John 17:7-8 (NASB), “Now they have come to know that everything You have given Me is from You; for the words which You gave Me I have given to them…”
And though he was the son, he earned the position of glory, honor, and immortality by proving his faithfulness. Hebrews 5:8-10 (CSB), “Although he was the Son, he learned obedience from what he suffered. After he was perfected…” Revelation 19:11-13, 16, “11 Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness, He judges and makes war. His eyes were like a flame of fire, and on His head were many crowns…and His name is called The Word of God…And He has on His robe and on His thigh a name written: KING OF KINGS AND LORD OF LORDS.”
