Understanding Bible prophecy encourages in two unique ways. First, it serves as a reminder that God controls history. When, you read from the pages of Scripture how He keeps His promises, your faith is strengthened… By reflecting on the fulfilled promises of the past, you can find great comfort as you look toward the future. Second, understanding God's promises for the future provides a solid foundation to which you can anchor your hope – a sturdy shield with which you can deflect your doubts and fears about tomorrow… When you reflect on God's plans and promises for you and for the world, you can face the future without fear.
John MacArthur
