National Day of Prayer

Today is the National Day of Prayer in the US. In honor of this day (which I feel pushes the boundaries of the Establishment Clause of the First Amendment of the US Constitution), Unreasonable Faith published this quote by a "Founding Father".

When a religion is good, I conceive it will support itself; and when it does not support itself, and God does not take care to support it so that its professors are obliged to call for help of the civil power, ‘tis a sign, I apprehend, of its being a bad one.
—Benjamin Franklin
