Matthew 7:12-14 - The Golden Rule
12 Therefore all whatever ye would that men should do to you, so also do ye to them; for this is the law and the prophets.
13 Enter ye in through the strait gate, for broad the gate and spacious the way leading to destruction, and many are they coming in through it. 14 For strait the gate and afflicted the way leading into life, and few are they finding it.
