Memory is one of the most important spiritual tools Christians can use in times of trouble. When crossing the Jordan into a new and marvelous (but equally intimidating) land, Joshua and the Israelites built memorials that would remind people of God's faithfulness for generations to come. Are you keeping a record of the ways God has been faithful? You will encounter something one day that seems BIG and you'll need a reminder of His faithfulness to give you the courage to move forward.
