The Teen Timeline—or T3—is a newly-released teen version of the revolutionary Great Adventure Bible Timeline learning system that hundreds of thousands of Catholic adults have used to learn the Bible. Dynamic teen presenter Mark Hart makes the Bible come alive for Catholic teens by unpacking God’s Word in a way they can relate to. T3 teaches teens the Bible by showing them the “big picture” of salvation history. When young students of the Bible first understand the “story,” they are eager to learn more. The net result: teens begin to wrap their minds and hearts around the Scriptures. They come to see the Bible as a relevant part of their lives.
