A tree and its fruits

The "Bible" and other religious books teach us to apply spiritual principles in our lives. When we meet people that don't apply spiritual principles in their lives or unto others that is a warning sign to look out for.

Watch out for false prophets. They come to you in sheep's clothing but inwardly they are ferocious wolves. By their fruit, you will recognize them.

Do people pick grapes from thornbushes or figs from thistles? Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus by their fruits, you will recognize them.

Matthew 7:15-20

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. Many 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?’

Then I will tell them plainly ‘I never knew you.

Away from me, you evildoers!’   Matthew 6:21-23
