Matthew 7:12-14 - The Golden Rule
12 All things therefore, as many as ye may want that men should do to you, so also do ye to them, for this is the law and the prophets.
13 Enter ye in by the narrow gate, because wide is the gate, and broad is the way, that leads to destruction, and many are they who enter through it. 14 How narrow is the gate, and restricted the way, that leads to life, and few are those who find it.
