The answer is: Angel of the Lord

Matt 1:20

In the Gospel of Matthew, just before the birth of Jesus, Joseph is faced with a dilemma after discovering that his fiancée, Mary, is pregnant. Historically, social norms dictate that an unmarried woman caught in such a situation faced severe stigma or even worse consequences. Yet, when Joseph is initially troubled, the Angel of the Lord intervenes by telling him not to be afraid of marrying Mary. This message showcases a theme present throughout the Bible: the importance of divine intervention during times of human anxiety and doubt.

Angels, in biblical literature, often serve as messengers carrying critical news or advice at pivotal moments. They appear frequently in the Old Testament, too, such as when an angel warns Abraham about the destruction of Sodom and Gomorrah or when an angel delivers a message to Hagar. This continuity highlights that whenever the foundational stories of faith seem shaky or uncertain, divine beings provide clarity and guidance.

It's also worth noting that the name "Jesus," given through the angel, means "God saves." This establishes from the start that Jesus’s purpose is woven deeply into the narrative as a figure of hope and rescue—laying the groundwork for everything that follows.

Engaging with these stories invites us to consider how uncertain decisions often bring forth greater possibilities than we initially foresee. It reminds us of the importance of faith when facing fear, a lesson that transcends time.
