God wants believers to serve Him in truth. In fact, it is this very issue that will determine “of what sort” our work is at the judgment seat of Christ.
No man is to be respected above another person in a form of unrighteous judgment. However, does not infer nondiscrimination in every matter.
There are times when we attempt to do the right thing only to have our motive judged as impure. In such times, we can learn much from David's example.
