Another gem from J. C. Ryle quotes:
I have but one request to make, and that is that you will persevere. I implore you to maintain your zeal and never let it go. I urge you never to stop doing the things you did at first, never to leave your first love, never let it be said of you that the things that you did in the first part of your Christian life were better than the things you did in your latter years. Beware of cooling down. All you have to do is to be lazy, and to sit still, and you will soon lose all your zeal. You will soon become another person from what you are now. Oh, don’t think that this is a needless exhortation!
