Take a moment to reflect on all the good that God has done in your life. All the answered prayers, all the kept promises every blessing you received and even the gift you have to life right this instant. These reflections will rekindle the hope you have in His deliverance of your life. You know He has done it before, you know He will do it again.
The Israelites take a moment to reflect on their victories. Joshua 12 also shows us the abundance of land to be given to the Isrealites.
