James 1:26
If anyone among you thinks himself to be religious while he doesn’t bridle his tongue, but deceives his heart, this man’s religion is worthless.

In context
Before · James 1:24–25
24for he sees himself, and goes away, and immediately forgets what kind of man he was. 25But he who looks into the perfect law of freedom and continues, not being a hearer who forgets but a doer of the work, this man will be blessed in what he does.
26If anyone among you thinks himself to be religious while he doesn’t bridle his tongue, but deceives his heart, this man’s religion is worthless.
After · James 1:27
27Pure religion and undefiled before our God and Father is this: to visit the fatherless and widows in their affliction, and to keep oneself unstained by the world.
