You shall know them by their fruit

Scripture references

Matthew 7:15–20 (ASV 1901)

15Beware of false prophets, who come to you in sheep’s clothing, but inwardly are ravening wolves. 16By their fruits ye shall know them. Do men gather grapes of thorns, or figs of thistles? 17Even so every good tree bringeth forth good fruit; but the corrupt tree bringeth forth evil fruit. 18A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. 19Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.

John 13:34–35 (ASV 1901)

34A new commandment I give unto you, that ye love one another; even as I have loved you, that ye also love one another. 35By this shall all men know that ye are my disciples, if ye have love one to another.

John 15:8 (ASV 1901)

8Herein is my Father glorified, that ye bear much fruit; and so shall ye be my disciples.
