1 John 4:4-6

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

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

6 We 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.
