What does the Bible say about Jesus being the God-man?

In Christian theology, particularly within the historic Reformed perspective, Jesus is recognized as the God-man. He is 100% God and 100% man, meaning that all the fullness of the Godhead dwells in Him bodily (Colossians 2:9). This union of divine and human natures is essential because it allows Him to be the perfect mediator between God and man. As God, He has the divine authority to save sinners, and as man, He can suffer and bear the sins of His people. The mystery of this union emphasizes that He is not merely a man with divine qualities but fully God and fully human, which is crucial for our understanding of salvation.
