When I do good I feel good, when I do bad I feel bad, and that's my religion.

Quoted in 3:439 Herndon's Lincoln (1890), p. 439: Inasmuch as he was so often a candidate for public office Mr. Lincoln said as little about his religious code as possible, especially if he failed to coincide with the orthodox world. In illustration of his religious code I once heard him say that it was like that of an old man named Glenn, in Indiana, whom he heard speak at a church meeting, and who said: "When I do good I feel good, when I do bad I feel bad, and that's my religion."
