2 POINTS of DISCERNMENT: Two simple things to look for: 1. King James Bible, 2. NON-OSAS. Those who use a corrupted new version of the Bible and/or teach OSAS (once saved always saved/ES = eternal security) are "blind guides" and leading others into the ditch of delusionment (Matthew 15:14; 23:16, 24).
"Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch." Matthew 15:14
"And he spake a parable unto them, Can the blind lead the blind? shall they not both fall into the ditch?" Luke 6:39
