Let me put it another way. There is a “stupid peace” and then there is a “smart peace.” The stupid peace comes from refusing to think about your overall situation. If you go that way, you can pop a cork, sit under a tree or on the beach, and try not to think about the grand scheme of things. But Paul is saying that if you are a Christian, you can think about the big picture, and as you do, you are going to find peace. And if you are a Christian, and you have no peace at all, it may be that you are simply not thinking.
