What happens in the 400 years between Malachi and Matthew? We fill in some of that history as we pivot from the Old Testament to the New in our exploration of 50 Books of the Bible in 50 weeks. We discuss the transition of Matthew, from hated tax collector to apostle, because of an encounter with Christ. Scriptures referenced include Amos 3:7; Matthew 9:9-13; Luke 19:10; and Matthew 15:24.
