Matthew 7:12-14 - The Golden Rule
12 Well then, whatever you would like men to do to you, do just the same to them; that is the meaning of the Law and the prophets.
13 Enter by the narrow gate: for [the gate] is broad and the road is wide that leads to destruction, and many enter that way. 14 But the road that leads to life is both narrow and close, and there are few who find it.
