What are you doing with the knowledge you have?

"I hold that it is unworthy of any man who possesses knowledge to keep his knowledge to himself, and rejoice in his own enlightenment, without making any effort to bring others to share in his privileges. Justly did the four lepers at the gate of Samaria feel their conscience smite them: 'We do not well; this is a day of good tidings, and we hold our peace.' [2 Kings 7:9] Had those to whom the light of Christianity was first given dealt so with our ancestors, we should still be lying in heathen darkness." (George Salmon, The Infallibility Of The Church [London, England: John Murray, 1914], 7)
