Words of Reassurance for Times of Doubt
I'm not a Calvinist, but I do (as all good Baptists do) believe in the Reformed doctrine of eternal security. John Piper has posted these helpful words of reassurance from J. Gresham Machen.
The question is not merely whether we can rest in our faith, but whether we can rest in the doubt that is the necessary alternative of faith. We pass sometimes through periods of very low spiritual vitality. The wonderful gospel which formerly seemed to be so glorious comes to seem almost like an idle tale. Hosts of objections arise in our minds; the whole unseen world recedes in the dim distance, and we think for the moment that we have relinquished the Christian hope....Fortunately, non-Calvinists may reap the tremendous benefits of this biblical truth as well. :-)
My mother [spoke to me] in those dark hours when the lamp burned dim, when I thought that faith was gone and shipwreck had been made of my soul. “Christ,” she used to say, “keeps firmer hold on us than we keep on him.”
My mother’s word meant...that salvation by faith does not mean that we are saved because we keep ourselves at every moment in an ideally perfect attitude of confidence in Christ. No, we are saved because having once been united to Christ by faith, we are his forever. Calvinism is a very comforting doctrine indeed. Without its comfort, I think I should have perished long ago in the castle of Giant Despair.(J. Gresham Machen: Selected Shorter Writings, 561)
