J.C. Ryle said this about prayer:
"Pray daily for a great outpouring of the Spirit on the Church and on the world. This is the grand need of the day—it is the thing that we need far more than money, machinery, and men. The "company of preachers" in Christendom is far greater than it was in the days of Paul; but the actual spiritual work done in the earth, in proportion to the means used, is undoubtedly far less. We need more of the presence of the Holy Spirit— more in the pulpit, and more in the congregation—more in the pastoral visit, and more in the school. Where He is, there will be life, health, growth, and fruitfulness. Where He is not—all will be dead, tame, formal, sleepy, and cold. Then let everyone who desires to see an increase of pure and undefiled religion, pray daily for more of the presence of the Holy Spirit in every branch of the visible Church of Christ." – J.C. Ryle
