Matthew 1:20-21 The Voice (VOICE)
This is remarkable, because Mary has never had sex. She and Joseph have not even spent very much time alone, but they are pledged to each other and their wedding feast has been planned.
She has never even kissed a man. She is a virgin, yet she is pregnant. Miraculous! On the other hand, Joseph suspects that Mary has cheated on him and had sex with another man. He knows he will have to break their engagement, but he decides to do this quietly. Mary understands that it is God, in the Person of the Holy Spirit, who has made her pregnant.
20 Now when Joseph had decided to act on his instincts, a messenger of the Lord came to him in a dream.
Messenger of the Lord: Joseph, son of David, do not be afraid to wed Mary and bring her into your home and family as your wife. She did not sneak off and sleep with someone else—rather, she conceived the baby she now carries through the miraculous wonderworking of the Holy Spirit. 21 She will have a son, and you will name Him Jesus, which means “the Lord saves,” because this Jesus is the person who will save all of His people from sin.
