How do we know when were saved? By examining ourselves. Looking into the "perfect law of liberty" as our mirror. To see your reflection. Let the word guide you in knowing what you are to do.
James 1:23-25 23 For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: 24 For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was. 25 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
