1 These are the nations the LORD left to test all those Israelites who had not experienced any of the wars in Canaan 2 (he did this only to teach warfare to the descendants of the Israelites who had not had previous battle experience) – Judges 3
God had left some trouble for Israel. Why? So that they would toughen up. So that they would gain some skills. They had no experience and needed some. They would fight in the future. They needed to be ready. As it were, they were inexperienced.
Maybe there are things in life that come our way just to teach us a lesson. Mr. Miage had Daniel(son) wash the car, paint the fence, and sand the deck. All preparation for a battle. At the time it seemed crazy. Unfair. Like nonsense. Training often seems like that. However, at go time, the opponent took a kick to the head and Daniel was champion. He learned how to fight in previous (and seemingly stupid) experiences.
Maybe some of the tough things that God is sending your way is neither punishment nor just the way life is. Maybe it is preparation for a future time. Do not waste the experience. Learn from it. The skills that you are developing now may be critical later.
