Punishment with Purpose
These are the nations the Lord left to test all those Israelites who had not experienced any of the wars in Canaan (he did this only to teach warfare to the descendants of the Israelites who had not had previous battle experience). Judges 3:1-2
There is purpose in everything, even in - especially in God's discipline. He is not a God who finds pleasure in punishing His children. Yet He understands that children raised in privilege often grow up with few coping skills for real life.
The Israelites were in the land promised to Abraham, and they quickly turned away from God to the gods around them. As discipline, the Lord did not remove all the peoples of the land. He knew that a nation that did not completely follow Him would disappear into the annals of history. Future generations would learn warfare by fighting the enemies in their midst.
Lord, there are enemies that I cannot seem to overcome. My heart cries out: "Why won't You deliver me completely?" Yet I think I understand. You know that if I cannot follow You alone, I will not survive the pull of the world. The presence of the enemy actually makes me stronger. His presence reminds me that I need You. His taunts and temptations teach me how to say "no." The weapons he uses against me teach me how to fight. Give me the strength to use what I have learned to defeat him. Help me to teach others the ways of warfare. Deliver me completely when I am ready to receive it. Help me to follow only You.
