Our culture has taught us that to love someone you need to accept them, all of them. Tolerance is key. The Bible teaches us the contrary. Love does not tolerate blatant sin. If someone, particularly a fellow believer, has a consistent sin issue: gossip, pride, anger, sexual immorality of any kind, slander, etc. it is our duty to say something.
“Honey, if your friends were jumping off a bridge would you jump too?” Sheepishly we mumble a no and usually go pout for a little while as our brains catch up to our hearts and we realize that our parents might maybe be a little bit right.
