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.
1 John 5:20
5:20 And we know that the Son of God has come and has given us insight to know him who is true, and we are in him who is true, in his Son Jesus Christ. This one is the true God and eternal life.
