When you speak the gospel, you share "the power of God for salvation to everyone who believes." Sharing the gospel is like walking around in a thunderstorm and handing out lightning rods. You don't know when the lightning will strike or who it will strike, but you know what it will strike—the lightning rod of the gospel. And when it does, that person's lightning rod will be charged with the power of God and he or she will believe.
