From best-selling author and Bible teacher Derek Prince comes a message that was near and dear to his heart: our responsibility as Christians to have an impact on the nations in which we live. In the Sermon on the Mount, Jesus laid out three important facts: as believers, we are to be (1) the salt of the earth, (2) the light of the world, and (3) a city set on a hill that cannot be hidden. The world is watching us; we cannot hide. As salt and light, Christians should be a source of both flavor and illumination that influences the world around them.
