One day in 1698, Robert Pyle of Pennsylvania decided to buy a black slave. The next night he dreamed of a steep ladder to heaven that he felt he could not climb because he carried a black pot. In the dream, a man told him the ladder was the light of Jesus Christ and would bear any whose faith held strong; otherwise, the climber would fall. Pyle woke that morning positive that he should eschew slaves and slavery, having equated the pot with the slave he wished to buy. In fact, so acutely did this dream awaken him to his sins that he became a dynamic advocate of liberation. This dream literally changed his outlook and his life.
