How does Joseph respond when he discovers Mary is pregnant? How does he respond when he learns her pregnancy has been caused by the Holy Spirit? He responds with righteousness and faithfulness before God! He is a quiet man who strives to do as God commands and takes on the task of being the earthly father of the Messiah, who he knows to be more than an ordinary man.
