In everything do to others as you would have them do to you; for this is the law and the prophets. “Enter through the narrow gate; for the gate is wide and the road is easy that leads to destruction, and there are many who take it. For the gate is narrow and the road is hard that leads to life, and there are few who find it.
Matthew 7:12-14 (nrsv)
The sign on the Narrow Gate:
Do to others
as you would
have them do to you
