J. Gresham Machen on False Ideas
"Christianity and Culture", in Princeton Theological Review 11 (1913), p.7.
False ideas are the greatest obstacles to the reception of the gospel. We may preach with all the fervor of a reformer and yet succeed only in winning a straggler here and there, if we permit the whole collective thought of a nation or of the world to be contolled by ideas which, by the resistless force of logic, prevent Christianity from being regarded as anything more than a harmless delusion. Under such circumstances, what God desires us to do is to destroy the obstacle at its root.
