James 1:26
“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.”
For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was.
But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
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.
