No such thing as "once bitten, twice shy" here. At least Eve was deceived... these people are just plain... (I better use something biblical) ...IGNORANT (as Paul would say). They should take a tip from Jesus and learn not to put God to a foolish test.
Like father, like son. If what they were doing what was Biblical, the father wouldn't've died and the son wouldn't have gotten sick
Mark 16 17 These signs will accompany those who believe: in my name they will cast out demons; they will speak with new languages; 18 they will take up serpents; and if they drink any deadly thing, it will in no way hurt them; they will lay hands on the sick, and they will recover.‚ÄĚ
