1 John 2:5-6; 1 John 2:24; 1 John 2:27-28 (Common English Bible w/ Apocrypha)

5 But the love of God is truly perfected in whoever keeps his word. This is how we know we are in him. 6 The one who claims to remain in him ought to live in the same way as he lived. 24 As for you, what you heard from the beginning must remain in you. If what you heard from the beginning remains in you, you will also remain in relationship to the Son and in the Father. 27 As for you, the anointing that you received from him remains on you, and you don't need anyone to teach you the truth. But since his anointing teaches you about all things (it's true and not a lie), remain in relationship to him just as he taught you.

Remaining until Jesus appears

28 And now, little children, remain in relationship to Jesus, so that when he appears we can have confidence and not be ashamed in front of him when he comes.
