Do you think the Puritans were frightening?

That's why they were Pur - itans. Purity of spirit, letting nothing complicate or confound the laws of God. Big problem for most Christians today is that you don't know the laws of God as well as you should. God hasn't changed any of those that were carried over into the new Covenant. If you don't know them you won't have any excuse if you die unsaved.
