'Dwell' in the Bible

If we say we have no sin [refusing to admit that we are sinners], we delude ourselves and the truth is not in us. [His word does not live in our hearts.]

As for you, let that remain in you [keeping in your hearts that message of salvation] which you heard from the beginning. If what you heard from the beginning remains in you, you too will remain in the Son and in the Father [forever].
