Matthew 7:12-14 - The Golden Rule
12 Do to others whatever you would wish them to do to you; for that is the teaching of both the Law and the Prophets.
13 Go in by the small gate. Broad and spacious is the road that leads to destruction, and those that go in by it are many; 14 For small is the gate, and narrow the road, that leads to Life, and those that find it are few.
