2 Thessalonians 3:13-15

Amplified Bible

¹³ And as for [the rest of] you, ^[a]believers, do not grow tired or lose heart in doing good [but continue doing what is right without weakening].

¹⁴ Now if anyone [in the church] does not obey what we say in this letter, take special note of that person and do not associate with him, so that he will be ashamed and repent. ¹⁵ Do not regard him as an enemy, but keep admonishing him as a [believing] brother.
