Who informed Joseph about Mary's pregnancy?

The story of Joseph learning about Mary's pregnancy is a profound and pivotal moment in the New Testament, encapsulating themes of faith, divine intervention, and the fulfillment of prophecy. According to the Gospel of Matthew, it was an angel of the Lord who informed Joseph about Mary's pregnancy. This revelation is found in Matthew 1:18-25, a passage that not only conveys the divine nature of Jesus' conception but also highlights Joseph's righteousness and obedience.

The narrative begins with a brief introduction to the circumstances surrounding Jesus' birth: "This is how the birth of Jesus the Messiah came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit" (Matthew 1:18, NIV). This verse sets the stage for the divine drama that is about to unfold. Mary, a virgin, is found to be with child, a situation fraught with social and personal implications for both her and Joseph.

Joseph, described as a "righteous man" (Matthew 1:19, NIV), initially decides to divorce Mary quietly to avoid public disgrace. This decision reflects his compassionate nature and adherence to the law. However, his plans are dramatically altered when an angel of the Lord appears to him in a dream. The angel's message is both reassuring and revelatory: "Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit" (Matthew 1:20, NIV). This divine intervention not only alleviates Joseph's fears but also places him at the center of God's redemptive plan.

The angel goes on to provide Joseph with further instructions and prophetic insight: "She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins" (Matthew 1:21, NIV). The name "Jesus" (Yeshua in Hebrew) means "The Lord saves," directly linking Jesus' identity with his mission of salvation. This moment is a fulfillment of Isaiah's prophecy: "The virgin will conceive and give birth to a son, and they will call him Immanuel" (Isaiah 7:14, NIV), which means "God with us." By referencing this prophecy, the Gospel writer underscores the divine orchestration of these events and the continuity between the Old and New Testaments.

Joseph's response to the angelic message is one of immediate obedience: "When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife" (Matthew 1:24, NIV). This act of faith and compliance is significant. Joseph's acceptance of Mary and her child not only protects them from societal condemnation but also fulfills his role in God's salvific plan. By naming the child Jesus, Joseph publicly acknowledges him as his own, thus incorporating Jesus into the Davidic lineage, which is crucial for the fulfillment of Messianic prophecies.

The account of Joseph's revelation is rich in theological implications. First and foremost, it affirms the virgin birth, a cornerstone of Christian belief that underscores Jesus' divine origin. The virgin birth is not merely a miraculous event but a theological statement about the nature of Jesus as both fully divine and fully human. As the Nicene Creed professes, Jesus is "begotten, not made, being of one substance with the Father." This doctrine is essential for understanding the incarnation, the belief that God became flesh in the person of Jesus Christ.

Secondly, the narrative highlights the role of divine revelation in guiding human actions. Joseph's dream is one of several instances in the Bible where God communicates through dreams and visions. This mode of revelation emphasizes God's sovereignty and the importance of faith in responding to divine guidance. Joseph's willingness to alter his plans based on the angel's message serves as a model of faithful obedience.

Moreover, the story illustrates the theme of God's faithfulness in fulfilling His promises. The reference to Isaiah's prophecy connects Jesus' birth to the broader narrative of God's covenantal relationship with Israel. It underscores the continuity of God's redemptive work from the Old Testament to the New Testament, affirming that Jesus is the long-awaited Messiah who brings God's salvation to fruition.

In addition to its theological depth, the account of Joseph's revelation offers practical lessons for contemporary believers. It challenges us to consider how we respond to God's guidance in our own lives. Joseph's example encourages us to trust in God's plan, even when it disrupts our expectations or requires personal sacrifice. It reminds us that faith often involves stepping into the unknown with the assurance that God is with us, as the name "Immanuel" signifies.

Furthermore, Joseph's story speaks to the importance of compassion and righteousness in our relationships with others. His initial decision to divorce Mary quietly reflects a desire to act justly without causing harm. His ultimate acceptance of Mary and Jesus models a love that transcends societal norms and personal convenience, embodying the self-giving love that Jesus himself would later teach and exemplify.

In conclusion, the angelic revelation to Joseph about Mary's pregnancy is a moment of profound significance in the New Testament. It affirms the divine nature of Jesus' conception, highlights the importance of faith and obedience, and underscores God's faithfulness in fulfilling His promises. Joseph's response to this revelation serves as a powerful example of righteous living and compassionate love, offering timeless lessons for believers today. Through this narrative, we are invited to trust in God's plan, embrace His guidance, and participate in His redemptive work in the world.
