How Can Jesus be God?
Before he came into the world as a man and was given the name Jesus, the Son was one with the Father in eternity past. He was not created, and he was not born from God in the sense that we think of children as being born of their parents. The Son always was and always will be. The Son and the Father are of the same substance; however, each serves a different role in the Trinity.
The Father, as the first person of the Trinity, initiated all Creation. When He spoke Creation into being (starting in Genesis 1:3), the Word He spoke through was the Son, the second person of the Trinity. (For a simple explanation of the Trinity, read this analogy of mine.) That is to say, the Son was the active agent by which all that was created, including you and I, came into being. Therefore, when the Son came into the world as Jesus, he was the Word made flesh, and he had power over his creation, such as raising people from the dead; commanding the wind and waves; healing the lame, blind, mute, leprous, and sick; walking on water; reading the thoughts of others; knowing the future; and a multitude of other miracles.
As the Son, Jesus receives his inheritance from the Father. His inheritance is to reign and rule over all Creation, and that is what he doing right now as he sits at the center of all reality. All that can be said of the Father can be said of the Son, in the same way (but to a vastly lesser degree) that a human bears likeness to his or her parents. Christ is omniscient, omnipotent, and omnipresent. He will provide, protect, heal, and shepherd us. He is Lord of lords and King of kings. He is Alpha and Omega, the beginning and the end. He has all power in his nail-scarred hands, and his Father is making for him a “footstool of his enemies” (Psalm 110:1) until the time of his return.
After conquering death, Christ received a glorified, imperishable body that still bears the crucifixion wounds. The saints will likewise receive imperishable bodies that will never decay or die. While we do not know the form of the Son prior to his entry into this world (he was a spirit), we do know that he now bears the resemblance of a man for all eternity. As our great High Priest, not only did Jesus bear the punishment for our sins so that we wouldn’t have to, he took on our likeness and is now the intercessor or mediator between man and the Father, between our weakness and the unfathomable glory of God, a glory that was, is, and will always be the Son’s as well because Jesus is God.
