Imagine you are Joseph, engaged to Mary. You are busy preparing a home to receive her. Then you discover that she is pregnant. You feel betrayed, deeply hurt. You are a righteous man who believes in faithfulness before marriage. That means that the both of you are to be virgins on your wedding night. But, you also believe in mercy because righteousness demands it. You contemplate breaking the engagement quietly, because you really love this woman and don’t want to disgrace her, nor have her punished. But you were not fully decided when you had a dream in which an angel said not to hesitate marrying Mary. Her pregnancy was of the Holy Spirit and would bring salvation. You marry her knowing you will be gossiped about, but that the child’s name would be “God saves” and “God with us”.
