If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain. Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.
When we are saved, one evidence of a true conversion is our speech. We should be kind and loving when we speak and show grace and mercy with our tongue.
Other evidences of our faith are shown in how we treat the orphans and widows and our purity. We should stand out in contrast to how the world is. People should be able to see something different in us and our behavior.
