Do you think Joseph could have fathomed the unexpected miracle God had in store as he pondered how to discard Mary after finding she was with child? He did not want to disgrace her, yet he must have been confused at first. Joseph had a strong faith. So strong he recognized the angel of God speaking directly to him in his dream about the whole situation. He first believed; then he obeyed.
No, Joseph probably did not have a clue about the unexpected miracle coming. Yes! Joseph trusted in the Word of God and went with it. His faith carried him through.
Unexpected miracles still happen today. Is your faith strong enough to recognize them?
Joseph was faithful to the law, and yet did not want to expose Mary to public disgrace, he had in mind to divorce her quietly. But after he had considered this, 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. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.” Matthew 1:19-20
