'Genuineness' in the Bible

holding to a form of [outward] godliness (religion), although they have denied its power [for their conduct nullifies their claim of faith]. Avoid such people and keep far away from them.

so that the genuineness of your faith, which is much more precious than gold which is perishable, even though tested and purified by fire, may be found to result in [your] praise and glory and honor at the revelation of Jesus Christ.
