I have examined all of the Bible as well as my narrow sphere, my straightened brains and my busy life would allow me. And the result is that the Bible is the best book in the world.

(taken from his letter to Thomas Jefferson, Christmas Day, 1813)
– John Adams (1735-1826), second president of the United States
