NT Bible Study 5: Angel Gabriel appears to Zacharias (Nativity of Jesus part 1)

This is a comparative Bible study on the events surrounding the Nativity of Jesus Christ. This first part focuses on the angel Gabriel's visit to Zacharias and his announcement of the future birth of John the Baptist. (Primary scripture reference: Luke 1:1-23.) Also, a question was posed regarding the covenant of an everlasting priesthood with Phinehas. [Other verses briefly mentioned: Matthew 1:1, Acts 1:1-2, Hebrews 7:11, Exodus 30:7-8, Leviticus 16:11-13, 1 Chronicles 24:1-19, Numbers 6:2-8, Daniel 8:16, Daniel 9:21, Ezekiel 3:26-27.] Overall this is our 5th New Testament (NT) Bible Study. I'm a layperson, hoping to witness things I believe I've learned through Bible study, and would like to share this information as a friend would with a friend.
