Matthew 7:12-14 - The Golden Rule
12 Therefore all things whatever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.
13 Enter ye in at the strait gate; for wide is the gate, and broad is the way, that leadeth to destruction, and many there are who go in by it. 14 Because strait is the gate, and narrow is the way, which leadeth to life, and few there are that find it.
