There are other Jesus' people proclaim who are not the real Jesus. There are other spirits who are not the Holy Spirit. There are different gospels than the real gospel. “But I am afraid that as the serpent deceived Eve by his cunning, your thoughts will be led astray from a sincere and pure devotion to Christ. For if someone comes and proclaims another Jesus than the one we proclaimed, or if you receive a different spirit from the one you received, or if you accept a different gospel from the one you accepted, you put up with it readily enough.” ‭‭2 Corinthians‬ ‭11‬:‭3‬-‭4‬ ‭ESV‬‬
