1 John 2:19-21 World English Bible (WEB)
19 They went out from us, but they didn’t belong to us; for if they had belonged to us, they would have continued with us. But they left, that they might be revealed that none of them belong to us. 20 You have an anointing from the Holy One, and you all have knowledge.[a] 21 I have not written to you because you don’t know the truth, but because you know it, and because no lie is of the truth.
