What does the Bible say about counterfeits in the church?

The Bible provides several warnings about counterfeits within the church, particularly in 2 Corinthians 11, where Paul expresses concern that false teachers have intruded, preaching a different Jesus and leading believers away from the true gospel. Paul emphasizes the importance of the true Jesus, asserting that salvation is entirely conditioned on Christ and not on human effort. The danger lies in the subtlety of these false teachers, who often present a sugar-coated version of the gospel that distracts from relying solely on Christ for salvation.
