James 2:4

Verse 4 Are ye not partial in yourselves?

In your recognition of the rich should you show a less cordial greeting to the poor? Are ye not partial? Can you doubt it yourselves? If you make any difference in your conduct toward either class, it is partial.

Become judges of evil thoughts.

The apostle further urges the sin that is committed in making a distinction between the rich and poor by showing the brethren that in so doing they are making judges of themselves, assuming a prerogative belonging to God alone. Now, if this idea is seized by the brethren herein rebuked, they will at once comprehend that in so conducting themselves they were simply harboring evil thoughts.
