Do not worry, the Holy Spirit will help, guide, and anoint us by His strength so that we have courage to reject any teachings which are not in line with Christ Gospel!
“Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? (Matthew 7:15-16)
