If we shouldn’t worry about anything, why are we worrying about terrorists? Would you listen to St Teresa of Avila telling you not to let them disturb you? Or is it just this war that you don’t want the pope to worry about? Is this a case of selective worrying?

"Does He not tell us to not concern ourselves with things over which we have no control?"

Yes. But we HAVE got control over our actions, haven’t we?

God has indeed got a plan. Trouble is, some of us think that God’s plan is the same as "our" plan, and that His will coincides with ours. Big mistake.
