Matthew 7:16-20

¹⁶You will know them by their fruits. Are grapes gathered from thorns, or figs from thistles? ¹⁷So, every sound tree bears good fruit, but the bad tree bears evil fruit. ¹⁸A sound tree cannot bear evil fruit, nor can a bad tree bear good fruit. ¹⁹Every tree that does not bear good fruit is cut down and thrown into the fire. ²⁰Thus you will know them by their fruits.
