An introduction to the Book of Luke, including its historical reliability and the case for Luke's authorship. When the angel Gabriel visits the virgin Mary to tell her she will bear the Messiah, Mary chooses to respond in faith and gratitude, despite the risk of legal prosecution and her husband's rejection of her testimony. Mary decides to present herself to God as a willing participant in his plan. This passage illustrates humans' ability and decision to willingly participate in God's Will for their lives or reject God's Will through refusal, failure to decide, or passivity.
