God is like the dad about to fix dinner. If he does it by himself, it will turn out perfect. But God takes the harder route, by asking for help from his children. The kitchen will get real messy, and the food will be somewhere between barely edible and mediocre. Yet the child will not only learn how to cook, but be excited to help dad in the kitchen.
God could achieve His mission without our help. Yet He seeks our help not for him, but for us. It’s all for us.
