Often we hear people describe God as having limited himself during the incarnation. Did the Son of God stop being omniscient, omnipresent, or fully God? 

Although it is common today to hear people speak of the Son of God limiting himself, this is actually not accurate. God’s nature is defined by boundlessness or infinity (infinitude). Our God’s greatness is unsearchable (Ps. 145:3; Job 5:9; Is 40:28). This unsearchableness describes his infinite nature. Psalm 139:7-12 likewise described God as omnipresent (filling space-time). Since God does not change (Malachi 3:6; Numbers 23:19; Psalm 102:27). 

Since God is boundless (infinite) and changeless, God cannot be less than God. God cannot be limited in any way. If Jesus were a limited version of God, he would not be true God. We know that, even during the incarnation, Jesus was true God. He was worshiped as God (Lk. 24:52), described as God (Matt. 8:29; 14:33), and functioned as God (Mk. 2:7-8).

Since Jesus was true God, even during the incarnation, we cannot say that he was limited in any way. If there was any limitation of God, then he would have ceased to be God. If Jesus was not true God, if the divine nature was limited, then the Son could not have made the Father known to people, the Son would not have been able to forgive sins by his own authority, the Son would not have been the divine sacrifice, and the Son would have been unworthy of worship. Since all of these attributes and actions are seen in the Son in the Gospels, we must say that Jesus was true God and that the divinity was true rather than limited. Even during the incarnation, the Logos was omniscient, omnipresent, and timelessly eternal.
