1 John 2:19

2:19 They went out from us, but they did not really belong to us, because if they had belonged to us, they would have remained with us. But they went out from us to demonstrate that all of them do not belong to us.

1 John 2:27

2:27 Now as for you, the anointing that you received from him resides in you, and you have no need for anyone to teach you. But as his anointing teaches you about all things, it is true and is not a lie. Just as it has taught you, you reside in him.
