...”2000 years and a billion followers tends to do that”...
Same with Islam....and they aren’t listening either.
You can say that again!
Satan existed before we did, it seems. For this reason I am never impressed with old religions he invented (or goaded open minds to invent). He’s been at the religion game for a long time. Just like him, they will be judged and destroyed FOREVER. Yet for reasons known only to God He allows Satan to develop and energize them and, yes, deceive millions. Scripture says these millions are deceived because they refuse to love the truth.
A person born of the Spirit can spot the fakes quite easily because of the wisdom God gives as a GIFT. You don’t get it in seminary. God drops it into your spirit by the Spirit. We are under no obligation to make sense of the devil’s nonsense. Just to steer clear of it and warn others of the wrath that is coming for all who do not know God.
