Matthew 1:18 ASV, Matthew 1:19-24 ASV and Matthew 1:25 ASV

At first it might seem a bit confronting that Jesus was conceived outside of wedlock (generally frowned upon in Christian teaching). Even though it was technically legit because of the whole Holy Spirit thing it must have been socially very controversial. It shows God's heart for those who are shunned an broken. He's so committed to them that he gave himself a fair dose of social issues during the incarnation.
Any though that we should only do ministry to solid nuclear families is thrown out the door.
