"What are you going to do, my brothers, in this great time of crisis? What a time it is to be sure! What a time of glorious opportunity! Will you stand with the world, will you shrink from controversy, will you witness for Christ only where witnessing costs nothing, will you pass through these stirring days without coming to any real decision? Or will you learn the lesson of Christian history; will you penetrate, by your study and your meditation, beneath the surface; will you recognize in that which prides itself on being modern an enemy that is as old as the hills; will you hope, and pray, not for a mere continuance of what now is, but for a rediscovery of the gospel that can make all things new; will you have recourse to the character of Christian liberty in the Word of God? God grant that some of you may do that! God grant that some of you, even though you be not now decided, may come to say, as you go forth into the world: 'It is hard in these days to be a Christian; the adversaries are strong; I am weak; but thy Word is true and thy Spirit will be with me; here am I, Lord, send me.'"
