Fasting and Prayer for Revival

I am sensible that somewhat considerable has been done in duties of this nature in some places, but I do not think so much as God in the present dispensations of his providence calls for. I should think the people of God in this land, at such a time as this is, would be in the way of their duty while doing three times as much at fasting and prayer as they do; not only, not principally, for the pouring out of the Spirit on those places to which they belong; but that God would appear for his church, and, in mercy to miserable men, carry on his work in the land, and in the world.
