The book of 1 John is replete with passages from the apostle admonishing us to abide in Christ. Some versions translate the word “abide” as “remain”. Both words convey what is at stake here. It’s not enough to believe in the gospel and accept Jesus as your Lord in a single moment in time. Those whose commitment to Christ is genuine will spend their lives seeking to be more like Jesus (1 John 2:6).
They will desire to abide in Him because they feel out of place anywhere else (Philippians 3:19-20; John 15:4-5). To remain in Him is to avoid being swayed by every false teaching, tossed about by any new so-called revelation (Ephesians 4:14). The Lord doesn’t want us to chase after religious fads or whims, but only to abide in Him (Colossians 2:6-7).
