"For there must be also heresies among you, that they which are approved may be made manifest among you." (1 Corinthians 11:19) Heresies have the same purpose as the truth - they separate the wheat from the chaff, the real from the counterfeit. According to 2 Thessalonians 2:10-12, It's irrefutable that the LORD takes it so personal when a person rejects His Word for a lie that He personally sends them "strong delusion" to help them believe that lie they've chosen and ultimately be damned. WANT A POWERFUL REVELATION? Look these up: Will heretics go to Heaven? No. The LORD told us to "REJECT" them and He will too if they don't repent (Titus 3:10). "heresies" are listed as 1 of the 17 soul damning sins of Galatians 5:19-21. See v 20. Also, according to 2 John 9, anyone who doesn't continue in sound doctrine is departed from Christ and hell bound. See also 2 Thessalonians 2:9-12 and 2 Timothy 4:3. Heresies are a choice. What did Jesus say to us in John 8:47? Oh and what about 1 Corinthians 11:19?
