The humanity and deity of Jesus must be equally understood without causing one aspect (deity or humanity) to infringe the other. Grudem states, “Jesus Christ was, and forever will be, fully God and fully man in one person. And that one person changed the course of history forever.” Heresy crops up whenever we allow our understanding of one aspect of Jesus to diminish another. Truly Jesus is a man like none other and he did change the course of history forever. How?
Jesus – a man like none other
To call his birth ordinary may seem unfair since he was conceived by the Spirit and so much is made of the manger and stable where he was born. Nevertheless, Jesus was born like every other person. He grew in the womb and his mother gave birth to him in that stable-delivery room.
That he grew physically is more easily grasped than his mental growth. We expect he must grow since we has born a baby. But don’t we often think that baby had the omniscient mind of God? The Scriptures teach he had to learn to walk and feed himself. Someone taught him reading, writing, and arithmetic. He increased in wisdom (Luke 2:52). Think about that – the God-man grew in wisdom! This is why, “In his human nature he did not know the day he would return to earth, ‘But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father’ (Mark 13:32).” Perhaps the best way to grasp Jesus’ humanity is to remember that he was like you in every respect as a human except he had no sin nature.
Jesus – a God man
Jesus’ true and full humanity did not make him a lesser God. Jesus was conceived in Mary by the agency of the Spirit of God. Therefore, he had a human nature and divine nature – no sin nature. Colossians 2:9 declares him to be fully God. This is essential because if he was not fully God he could not have fully taken the payment for sin. That Jesus is God is seen in his authority, power over creation, power over spirit beings (demons), power over death, power over disease, and knowledge of men’s thoughts.
What do you think?
How does Jesus being fully God encourage you? In what ways are you encouraged by Jesus’ full humanity? What would cease to be true for you spiritually if either of these aspects were not true?
