It is the very height of irrationality and arrogance to call Christ Lord with the lips while utterly defying Him with one’s life. Yet that is precisely how multitudes live (Luke 6:46). Such people are even more preposterous examples of self-contradiction than the atheist who imagines he can deny the Source of all that’s good and yet somehow be “good” himself. ~John MacArthur, The Jesus You Can’t Ignore
