On the Feast of Nativity, the Church celebrates the birth of Christ, a mystery that surpasses the human mind: God was incarnate and became Man. Of this incredible event, the prophets foretold hundreds of years before it happened: the details of the where, how, and why. The Lord is in our midst. He is with us-Immanuel, God with us. In this book, His Eminence Metropolitan Youssef explains the reasons for the incarnation and the significance of being born in Bethlehem, and discusses some of the prophecies and liturgical symbols of the incarnation. When we learn about this wondrous mystery, feelings of love, peace, joy, and gratitude overwhelm our hearts, and we cannot help but sing with the angels, saying, "Glory to God in the highest, and on earth peace, goodwill toward men!"
