Joseph and Mary

Matthew 1

20 . . . an angel of the Lord appeared to him in a dream and said, “Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. 21She will give birth to a son, and you are to give him the name Jesus,[c] because he will save his people from their sins.”

. . .

24When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife.

Joseph was engaged to Mary and planning to marry Mary. But, Mary became pregnant with Gods child and Joseph does not want to marry her. So, he had a dream and an angel told him that Jesus is going to be born from Mary and that he should marry Mary and take care of the baby and Mary. So, Joseph obeyed God and did the same.
