Joseph planned a quiet and respectful divorce for Mary, not believing that her baby was from God (who would to be fair!). He needed to be convinced. So, God showed up in his dream and explained the whole situation. Without hesitation he obeys what God has asked him to do. Like Mary, an act of radical faith and obedience is what we see of Joseph’s response to God’s instruction. Trusting that God is in control and risking the shame and loss of reputation it could bring to him and his family.
