I have this excellent collection of Puritan sermons next to my reading chair. Six volumes, each weighing in at over 600+ pages. I was reading from it this week and wanted to share a quote. From a sermon on Mt. 5:16,
Christ here intendeth that we must abound especially in those good works which the world is capable of knowing to be good, and not only in those which none but Christians themselves approve. If believers and unbelievers agreed in no common principles, we were not capable of preaching to unbelievers, nor convincing them, nor of conversing with them. Richard Baxter, What Light Must Shine in Our Works?
