Matthew 7:12-14

12 All those things, then, which you would have men do to you, even so do you to them: because this is the law and the prophets.

13 Go in by the narrow door; for wide is the door and open is the way which goes to destruction, and great numbers go in by it.

14 For narrow is the door and hard the road to life, and only a small number make discovery of it.
