Discerning false prophets by their "fruit" (Matthew 7:15-20) — fruit is defined IN the passage as whether their teaching leads people to do God's will vs. lawlessness. It's not about charismatic experiences or emotional reactions.

The passage itself defines fruit: v.21-23 shows people who prophesy, cast out demons, do mighty works but Jesus says "I never knew you; depart from me, you workers of lawlessness." So fruit is NOT miraculous signs or emotional experiences. Fruit is whether their teaching produces obedience to God or lawlessness. Being "drunk in the Spirit" is not biblical — Acts 2 says they were ACCUSED of being drunk, not that they acted drunk.
