Beware of false prophets, who come to you in the clothing of sheep, but inwardly they are ravening wolves. 16By their fruits you shall know them. Do men gather grapes of thorns, or figs of thistles? 17Even so every good tree bringeth forth good fruit, and the evil tree bringeth forth evil fruit. 18A good tree cannot bring forth evil fruit, neither can an evil tree bring forth good fruit. 19Every tree that bringeth not forth good fruit, shall be cut down, and shall be cast into the fire. 20Wherefore by their fruits you shall know them. 21Not every one that saith to me, Lord, Lord, shall enter into the kingdom of heaven: but he that doth the will of my Father who is in heaven, he shall enter into the kingdom of heaven. 22Many will say to me in that day: Lord, Lord, have not we prophesied in thy name, and cast out devils in thy name, and done many miracles in thy name? 23And then will I profess unto them, I never knew you: depart from me, you that work iniquity.
