Why do some teachers distort the gospel?

In Jude 4, it is noted that certain individuals have crept in unnoticed, turning the grace of God into a license for immorality and denying Christ. These false teachers operate out of selfish motives, seeking to exploit their followers for personal gain, rather than preaching the truth of the gospel. They may appeal to human desires and offer false assurances, leading people away from the core message of Christ's sacrifice and the need for repentance. Recognizing these distortions is crucial for Christians, as it helps protect the integrity of the gospel and keeps believers anchored in the truth.
