Here's an excerpt:
It is true that the decisive thing is the regenerative power of God. That can overcome all lack of preparation, and the absence of that makes even the best preparation useless. But as a matter of fact God usually exerts that power in connection with certain prior conditions of the human mind, and it should be ours to create, so far as we can, with the help of God, those favorable conditions for the reception of the gospel. 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 the nation or of the world to be controlled 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. . . . What is today a matter of academic speculation begins tomorrow to move armies and pull down empires. In that second stage, it has gone too far to be combated; the time to stop it was when it was still a matter of impassioned debate. So as Christians we should try to mold the thought of the world in such a way as to make the acceptance of Christianity something more than a logical absurdity. . . . What more pressing duty than for those who have received the mighty experience of regeneration, who, therefore, do not, like the world, neglect that whole series of vitally relevant facts which is embraced in Christian experience -- what more pressing duty than for these men to make themselves masters of the thought of the world in order to make it an instrument of truth instead of error?
