A key belief in Christianity is that of Christ’s nature. We believe Christ was fully man and fully God. John begins his book with reaffirming this truth, reminding us all of Jesus’s divine nature.
"In the beginning was the Word, and the Word was with God, and the Word was God." - John 1:1
The book of John, of course, has several references to his divine nature - 5:18, 8:24, 8:58 to name a few. So what of his human nature? There’s probably just as many, if not more evidences in scripture. Not only do we see verses that talk about him being made flesh (1 John 4:2, 2 John 7), we also see he has real human needs such as hunger (Matthew 4:1-2), and human reactions and emotions. (John 11:33-35)
This state of Jesus being both God and man is what we call the hypostatic union. While this word may not appear in the Bible, it is a term that serves as a shorthand to help us acknowledge this common belief. So why is this significant? Why does it matter if he was just one or the other or both?
Jesus was sent to pay the price we couldn’t pay for our sin. In order to do this, he had to be in a state where he was able to be a suitable substitute for us. This required him to be fully man. On the same note, he was not able to set aside his divine nature, nor should he have - through his divine nature, he was able to supernaturally reject sin in his life and ultimately defeat it in his death.
It also means that when we pray, we don’t pray to someone unfamiliar with the intricacies of being human (Hebrews 4:14-15). Even before the incarnation, God was all-knowing, but his coming and experiencing of humanity can serve as a comfort to us.
