I've often thought about Joseph, Mary's husband. He must have been a remarkable man, very good, very loving, very faithful.
Adoption has played a big part in my family, my sister and two nephews are mine through adoption. From this perspective, it's very sweet to think of Jesus being raised by an adopted father. Not his actual father, but a man who took on this child, and his mother, and gave them a family.
Here is the dream that Joseph had while trying to decide what to do after learning that Mary was having a baby.
20 But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.
21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
22 Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying,
23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
24 Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife:
25 And knew her not till she had brought forth her firstborn son: and he called his name JESUS.
