Heb 11:30-31.Josh 6:1-25. The author of Hebrews tells us that the Jericho walls came tumbling down because of faith.

How many times in our own lives may the presence or absence of a living faith make all the difference? Rahab, an unlikely hero, serves as an amazing example of faith that made a difference to her household.
