Matthew 7:12-14 - The Golden Rule
12 "Therefore everything that you would have men do to you, do you also the same to them; for this is the Law and the Prophets.
13 "Enter by the narrow gate; for broad is the gate and wide the road that leads to destruction, and many are they who go in by it; 14 "but the gate is narrow and the road is steep, which leads to life, and they are few who find it.
