Mat 1:18 Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
Mat 1:19 Then Joseph her husband, being a just man, and not willing to make her a publick example, was minded to put her away privily.
Mat 1:20 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.
I can't think of many harder jobs than being the foster father of God. No pressure! What faith it must take to still marry a pregnant woman you know you sure didn't sleep with. It wasn't any more possible for a woman to get pregnant then without having sex than it is now, and Joseph must have known that. There was no way he could explain away this miracle without complete faith in God.
Then your wife has this baby, and you have to flee from where you're living lest your leaders slaughter the baby along with all the other children he kills attempting to find your son. We think we have stress!
