Matthew 7:10-20

10 or if he shall ask for a fish, will give him a serpent?

11 If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father who is in heaven give good things to them that ask him?

12 All things therefore whatsoever ye would that men should do unto you, even so do ye also unto them: for this is the law and the prophets.

13 Enter ye in by the narrow gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many are they that enter in thereby.

14 For narrow is the gate, and straitened the way, that leadeth unto life, and few are they that find it.

15 Beware of false prophets, who come to you in sheep's clothing, but inwardly are ravening wolves.

16 By their fruits ye shall know them. Do [men] gather grapes of thorns, or figs of thistles?

17 Even so every good tree bringeth forth good fruit; but the corrupt tree bringeth forth evil fruit.

18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.

19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.

20 Therefore by their fruits ye shall know them.
