1 John 2:5-6; 1 John 2:24; 1 John 2:27-28

5 But the charity of God is perfect verily in him, that keepeth his word [Forsooth who keepeth his word, verily in him is perfect charity]. In this thing we know, that we be in him, if we be perfect in him. 6 He that saith, that he dwelleth in him, he oweth to walk, as he walked.
24 That thing that ye heard at the beginning, dwell it in you [That thing that ye heard from the beginning, dwell in you]; for if that thing dwelleth in you [for if it shall dwell in you], which ye heard at the beginning, [and] ye shall dwell in the Son and in the Father.
27 and that the anointing which ye received of him, dwell in you. And ye have not need, that any man teach you, but as his anointing teacheth you of all things, and it is true, and it is not lying; and as he taught you, dwell ye in him. 28 And now, ye little sons, dwell ye in him, that when he shall appear, we have trust, and be not confounded of him in his coming.
