On a serious note, seeing all those people clapping is a good reminder that when you are exposed to a false representatives use that as a time to reflect on yourself. What did you agree with leading up to the statement or action that tipped you off that this person was not a true follower of Christ.
Find out if what was said is actually supported by the Bible in context. The devil will mix truth and lie. And the lies that he chooses are often designed to appeal to the parts of our nature that we are refusing to give to God. Did you fall for any lies? What is the idol that those lies were appealing to?
I came across a literal false prophet once. As in she had people lining up a few times a year to ask for personal prophesies kind of false prophet. I visited her church 2-3 times before I realized what was up. I mainly attended bc my friends who were very religious went and I didn’t have a church that I liked in town.
It was almost three years later when I realized that I did not have a spirit of forgiveness. I also realized that I enjoyed one of her sermons because she literally was not preaching true forgiveness. She was preaching “seek a different form of payment from that person” in the form of “ask God to give them ‘their just desserts’ in this life” etc. Just ignoring that we should be forgiving others of their debts to us as we ask God to forgive our debts as well. As well as the fact that God’s primary concern is being with his children, not handing out “time-outs” over petty fights. She spun a whole sermon to get to that non-Christ-like conclusion and to make it more palatable.
That’s a basic move from the devil’s playbook. However, it is very effective because you only see through it easily if you don’t have an idol that it is appealing to.
