WHY WE'RE TEMPTED TO GIVE UP:
Now the gates of Jericho were securely barred because of the Israelites. No one went out and no one came in. Then the Lord said to Joshua, “See, I have delivered Jericho into your hands…”

So Joshua ordered the army, “Advance! March around the city, with an armed guard going ahead of the ark of the Lord … But do not give a war cry, do not raise your voices, do not say a word until the day I tell you to shout. Then shout!” So he had the ark of the Lord carried around the city, circling it once. Then the army returned to camp and spent the night there. Joshua got up early the next morning and the priests took up the ark of the Lord … So on the second day they marched around the city once and returned to the camp. They did this for six days.

On the seventh day the Israelites got up at dawn and marched around the town as they had done before. But this time they went around the town seven times. The seventh time around, as the priests sounded the long blast on their horns, Joshua commanded the people, “Shout! For the Lord has given you the town!” ... When the people heard the sound of the rams’ horns, they shouted as loud as they could. Suddenly, the walls of Jericho collapsed, and the Israelites charged straight into the town and captured it.
