The central message of the sermon is that in order for Jesus to relate to humanity, connect with us, and atone for our sins, he must demonstrate his true humanity. The teacher argues that if Jesus is God, as affirmed by Christianity, then how can he also be human? The answer lies in Jesus' identification with humanity through various aspects of his life, including his baptism, genealogy, and temptation. This identification shows that Jesus has the right to pay for our sins, sympathize with us on a gut level, and connect with us emotionally. The sermon draws upon ancient creeds, particularly the Definition of Chalcedon, which affirms Jesus' dual nature as both fully God and fully human. By emphasizing Jesus' humanity, the teacher advances the idea that true salvation requires a savior who is not just divine but also genuinely human. Ultimately, the takeaway for listeners is that they must understand Jesus' humanity in order to grasp his role as our Savior.
