Hyper grace…Apostasy?

Is Hyper grace a form of apostasy? Speaking of "Deception", how can we identify a perversion of the truth from whomever we listen to? Or let's just say, how can we actually know if the preacher on the pulpit is a real servant of God? We have been forewarned about their infiltration: “ungodly persons who pervert the grace of our God into licentiousness”

As always, I would highly appreciate your insights in the comment sections. Thanks!
