'Believers' TRY to do the right thing as a thank you & because we are saved but not to be & OR remain saved. The ONLY condition to be saved is FAITH. What happens then if a believer changes their mind & stops believing ? I've listened to Greek knowledgeable Pastors teach that faith MUST be ongoing. 2 Tim 2:13 & Eph 1:13 though appears to nullify that claim.
