Before he spoke, Piper asked God for “a prophetic word that would have a ripple effect to the ends of the earth and to eternity.” — that prayer was absolutely answered in my life personally. If you haven’t ever listened to John Piper talk about seashells, do yourself a favor a take 7 minutes and listen to it in the linked story and ready the story behind it as well. It is a beautiful illustration about how one person can dream up a big crazy prayer and how God can answer it!
