So you can tell them by their fruit.
"You must either make the tree sound and its fruit sound, or make the tree bad and its fruit bad; a tree is judged by its fruit.
2 Peter 2:10
especially those who yield to their physical nature and indulge in passions that defile them, and despise authority. Rash, headstrong men! They stand in no awe of majesty, but deride beings
But these people deride anything they do not understand, and the things they know by instinct, like unreasoning animals, they use for their own destruction.
For sound trees do not bear bad fruit, nor bad trees sound fruit.
Can a fig tree produce olives, my brothers, or a grape vine figs? A salt spring cannot give fresh water.
