Erlo Stegen emphasizes the profound significance of Jesus' birth in Bethlehem, a seemingly insignificant town that became the birthplace of the eternal Ruler. He explains that understanding God fully is impossible, as He transcends human comprehension, much like a child cannot grasp advanced concepts. Stegen illustrates the Trinity with relatable examples and highlights the transformative power of Jesus, who elevates the humble and makes something of those who are nothing. He recounts the rich history of Bethlehem, including the stories of Ruth and David, culminating in the birth of Jesus, who came to identify with the lowly and offer salvation. The sermon concludes with a call to embrace the eternal life offered through Jesus, the bread of Bethlehem.
