“More and more am I jealous lest any views upon prophecy, church government, politics, or even systematic theology, should withdraw one of us from glorying in the cross of Christ”

Man’s fall, his need of a new birth, forgiveness through an atonement, and salvation as the result of faith, these are our battle-ax and weapons of war. We have enough to do to learn and teach these great truths, and accursed be that learning which shall divert us from our mission, or that willful ignorance which shall cripple us in its pursuit. More and more am I jealous lest any views upon prophecy, church government, politics, or even systematic theology, should withdraw one of us from glorying in the cross of Christ.
