What is the use of arguing over something like sola fides when so many people out there need the help of humble and loving Christians who have the capabilities to grant said help whichever way they can? None. There is no point in debating about the letter of the law when the spirit of the law is clearly being taken for granted.
Christ gave us new life in rising from the dead, triumphing over sin so that we can hope in eternal life. It is our duty and calling, therefore, to make the most of this opportunity for His greater glory.
