In this sermon on Matthew 1:18-25, Pastor Nate Holdridge explores the most foundational question of the Christian faith: "Who is Jesus?" By examining the angelic announcement to Joseph, we discover that Jesus' identity is threefold: he is fully human, fully God, and the long-awaited Son of David. Pastor Nate explains how this unique identity is the necessary foundation for Jesus' purpose—to be Immanuel, "God with us," and to save His people from their sins. This teaching challenges us to find our ultimate identity not in our performance or affiliations, but in the person and mission of King Jesus.
