JMNT(i)
23 Everyone continuously denying or turning his back on the Son does not even have (or: not even is he possessing; neither holds) the Father. The one habitually speaking like the Son (or: the one continuously confessing and avowing the Son; the one habitually speaking in accord with or saying the same thing as the Son) also constantly has (possesses) the Father.
24 As for you folks, let what you heard from [the] beginning be continuously remaining (abiding; dwelling; staying) within you. When (or: If; If at any time) that which you heard from [the] beginning would remain (should abide; can dwell; may stay and make its home) within you, you also will continue remaining (abiding; dwelling; staying) within the Son, even within the midst of and in union with the Father! (or: you will dwell both in the Son and in the Father).
