1 John 2:23-25

New Catholic Bible

²³ Whoever denies the Son
does not have the Father,
but whoever acknowledges the Son
has the Father also.
²⁴ Let what you heard from the beginning
remain in you.
If what you heard from the beginning
remains in you,
then you will remain in the Son
    and in the Father
²⁵ And this is the promise he made to us:
eternal life.
