How do we know that Jesus is fully human?

The doctrine of the Incarnation states that Jesus is fully God and fully man. Hebrews 2:14 states that He partook of the same flesh and blood as His people, signifying that He was genuinely human. He experienced human emotions and physical sensations, such as hunger and thirst, as noted throughout the Gospels. His ability to be tempted 'in all points as we are' further underscores His authentic humanity, though He remained without sin. This unique union of the divine and human within Christ is essential for our understanding of how He can be both our Savior and our example.
