Matthew 7:12-14 - The Golden Rule
12 In everything, treat others as you would want them to treat you, for this fulfills the law and the prophets.
13 "Enter through the narrow gate, because the gate is wide and the way is spacious that leads to destruction, and there are many who enter through it. 14 But the gate is narrow and the way is difficult that leads to life, and there are few who find it.
