1 John 4:4-6

4You are of God, little children, and have overcome them, because He who is in you is greater than he who is in the world.

5They are of the world. Therefore they speak as of the world, and the world hears them.

6We are of God. He who knows God hears us; he who is not of God does not hear us. By this we know the spirit of truth and the spirit of error.
