God sent the children of Israel out to battle. Each day they went out and each day they came back defeated. Thousands died. They courageously formed the same battle line day after day until they finally defeated the enemy. God sometimes asks us to do things even when it is costly to do them. Perhaps the victory He desires isn't so much that we are never knocked down, but the courage to keep getting up every time we are.
“But the people, the men of Israel, took courage, and again formed the battle line in the same place where they had formed it on the first day.” Judges 20 ESV Conversations Within” ts 2/3/
