1 John 5:21 (KJV)

What does 1 John 5:21 mean?

1 John 5:21 is a direct warning from the apostle John, urging his readers to guard themselves against idols—anything that could take the place of God in their lives. The verse closes the letter with a simple but strong reminder to stay faithful and not let anything else become the focus of their devotion.

John is writing to a community of believers he cares for deeply, calling them "little children" as a term of affection and guidance. In the context of the letter, John has been emphasizing the importance of knowing the true God and living in His love. This final instruction sums up his concern that nothing—whether physical objects, false ideas, or misplaced priorities—should distract them from their relationship with God.

The Greek behind 1 John 5:21

• τεκνία (teknia, G5040): This word is translated "little children" and is an affectionate term John uses for his readers, showing his pastoral care and close relationship with them.
• φυλάσσετε (phylassete, G5442): Translated "keep," this Greek word means to guard or protect. John is not just suggesting avoidance but an active, ongoing effort to stay away from idols.
• εἴδωλα (eidōla, G1497): The word for "idols" refers to images or objects of worship, but in the context of John's letter, it can also mean anything that takes God's rightful place in a person's heart.
