Matthew 24:24 New International Version
"For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect."
Yes, guest a minister came to my church ... during the summer when Portland was on fire, they had the audacity to "explain" hate and anger were ok, "They are in the Bible" and read a verse here and there to prove that its ok to be angry and hate. Horrified, I left immediately. I did write to the rector for months looking for a kind of admonition, instead I found complicite behavior. You know in your heart who is good / righteous, its easy to discern.
Righteous anger is biblical. Hatred though is poisonous. It's a fine line of separation.
