And many will choose to be self righteous, not passing on a genuine word of saving faith. Some of those won’t believe at all and be damned as described; others will barely believe and have a scanty reward.
Only God knows a person’s heart and what he/she thinks. It’s best to work out our own salvation and pray for the others.
If one is a self righteous Christian beware because The LORD just might allow you to commit a sin that destroys your self righteousness. The LORD will humble you. He lifts up the humble, but puts down the proud.
