The answer is: Angel of the Lord

Matt 1:20

The moment Joseph learns that Mary, his betrothed, is pregnant, it's easy to see why he struggles with fear. In Jewish culture, betrothal was a serious commitment, akin to marriage itself. Joseph's confusion could lead to an avalanche of public shame for Mary. However, this angelic visitation used characteristically celestial warmth and encouragement to dissolve his fears. "Do not be afraid!" is a recurring phrase in the Bible, often appearing when divine beings share important news—both comforting and guiding.

Interestingly, dreaming is central to Joseph's story. This dream is just a sneak peek into a long tradition of divine messages delivered in slumber, not only seen in the story of Jacob (who was warned via a dream about his future) but lasting all the way to the New Testament. Plus, the very name of Immanuel, Jesus’ designation, means "God with us." It highlights Christianity's foundational belief, experiencing the divine presence in everyday life.

It's engaging to note that Joseph isn't as prominent as Mary in the narratives, yet without his willing acceptance of the angel's message, the story would have unfolded quite differently. Beyond mere obedience, this evokes ideas of trust and active decisions that resonate throughout the Bible. Ultimately, Joseph’s actions inspire many to embrace their life situations with courage, often reiterating the message: we’re never alone when big choices come our way!
