How come Jesus is God but He didn’t know the end time?

Jesus does say that even he doesn’t know the day or hour of his coming (“…no one knows, not even the angels of heaven nor the Son, but the Father only”) (Mat. 24:36. Also Mark 13:22). Yet as God he is supposed to be all-knowing. Does that then mean he isn’t God?

No, it doesn’t mean that He is not God.

This text is not the only text that shows non-divine or non-God actions, experiences and words from Jesus. There are many. Jesus fell asleep in the boat (Mat. 8:24), yet God neither slumbers nor sleeps (Ps. 121:4). He was “weary from his journey” (Jn. 4:6) yet God is almighty (Gen. 17:1). He feels great sorrow on his heart (Mat. 26:38) while God doesn’t have such human passions (Acts 14:15). He dies, while God is immortal. One very important way that Jesus is unlike God is that Jesus has a physical form, whereas God is invisible (1 Tim. 1:17) and “no one has ever seen God” (Jn. 1:18).

These facts show that Jesus experienced a humanity similar to ours. He was “made like his brothers in every respect” (Heb. 2:17), except for sin. Since humanity and deity are two different things, we have to remember that as far as he was Man (and he still is, though now in the exalted humanity that we will have when we are glorified) he is not God. Yet at the same time, other Bible passages show clearly that Jesus was and is God. And as far as he is God, he is not Man!

Here are a few examples of passages stressing Jesus’ deity:

He is the Creator (John 1:1-3) yet man is created. He is named God (Rom. 9:5, Tit. 1:13, Heb. 1:8, Is. 9:6, Is. 43:11, etc.). He is worshipped as God and he receives such worship (Rev. 5:13, John 20:28-29). He possesses the attributes of God (Rev. 22:12-13, Col. 1:17, Jn. 16:30, etc.) He and the Father are both the source of divine blessings (Phil. 1:2, Gal. 1:3, etc.)

Jesus has two natures – that of God and that of Man. These two natures are both His, and so we say he is both God and Man. When we read a text affirming his deity (e.g. “Before Abraham was, I AM”), the text does not deny his humanity. And when we read a text affirming his humanity (e.g. “He gave up His Spirit”), it does not deny his deity. Jesus is One Person (i.e. the second Person of the Trinity) but two nature. (He has to be both to be able to accomplish our salvation. He the man that is be our priest before God (the book of Hebrews), and he is God descended to reveal himself to man and save man (the book of John).

To show you how Christians have articulated this in history, here is a sample from the Athanasian Creed (6th C) and the Chalcedonian Creed (5th C):

The Athanasian Creed (6th Century):

“Furthermore it is necessary to everlasting salvation; that [w]e also believe faithfully the Incarnation of our Lord Jesus Christ. For the right Faith is, that we believe and confess; that our Lord Jesus Christ, the Son of God, is God and Man; God, of the Essence of the Father; begotten before the worlds; and Man, of the Essence of his Mother, born in the world. Perfect God; and perfect Man, of a reasonable soul and human flesh subsisting. Equal to the Father, as touching his Godhead; and inferior to the Father as touching his Manhood. Who although he is God and Man; yet he is not two, but one Christ.

Chalcedonian Creed (451AD)

We, then, following the holy Fathers, all with one consent, teach men to confess one and the same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man.
