How do we know that Jesus Christ is both God and man?

The doctrine that Jesus Christ is both God and man is a core tenet of Christian faith. According to 1 Timothy 3:16, God's manifestation in the flesh indicates that He is fully human and fully divine. The very fact that He lived, died, and was resurrected reassures us of His dual nature. This mystery is profound; it reveals that He was not merely an example for us but rather the necessary mediator who took on human nature to fulfill the law's demands by suffering and dying in our place. This doctrine assures believers that, through Christ, God Himself knows our struggles and weaknesses.
