Matthew 7:15-23 (New International Version)

A Tree and Its Fruit

 ¹⁵"Watch out for false prophets. They come to you in sheep's clothing, but inwardly they are ferocious wolves. ¹⁶By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles? ¹⁷Likewise every good tree bears good fruit, but a bad tree bears bad fruit. ¹⁸A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. ¹⁹Every tree that does not bear good fruit is cut down and thrown into the fire. ²⁰Thus, by their fruit you will recognize them.

 ²¹"Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven. ²²Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name, and in your name drive out demons and perform many miracles?' ²³Then I will tell them plainly, 'I never knew you. Away from me, you evildoers!'
