Acceptable Sins

Revelation 2:18–29


Lesson Objectives

  1. Understand that no church is perfect, but every church must pursue holiness.
  2. Identify the dangers of tolerating sin and allowing worldly standards to influence the church.
  3. Recognize the call of Christ to repent and resist sinful compromise.
  4. Strengthen personal faith, love, and service as marks of a faithful Christian life.
  5. Embrace the promises of authority and eternal victory for those who overcome.

Introduction

What does the perfect church look like on this earth? Is there such a thing as a perfect church?
Most Christians will admit that no church on this earth is perfect. As long as imperfect people make up the church, there will be issues that must be confronted.

Revelation 2:18–29 introduces us to the church at Thyatira—a congregation much like many today: strong in many virtues, yet compromising in others.
The message is clear: strengthen what is weak and continue doing what is good.


I. What Does Jesus Know? (Revelation 2:18–19)

Application:


II. The Danger of Tolerating Sin (Revelation 2:20–21)

Despite their good deeds, Jesus rebukes Thyatira for tolerating sin.

  1. They tolerated a false prophetess called “Jezebel.”
    • The name recalls Ahab’s wife who led Israel to idolatry and persecution of prophets (1 Kings 16).
    • This modern “Jezebel” seduced the church into immorality and compromise.
  2. When sin is winked at, it soon becomes normalized.
  3. Many churches today have “acceptable sins”:
    • Sexual immorality before marriage
    • Living together without marriage
    • Pornography, affairs, homosexuality
    • Immodesty, drunkenness, profanity
  4. The danger: repeated sin hardens the conscience. People no longer feel guilt or see anything wrong with sinful actions.

    “Do not be deceived: ‘Bad company corrupts good morals.’” (1 Corinthians 15:33)
    “Certain persons have crept in unnoticed… who turn the grace of our God into licentiousness.” (Jude 1:4)

Application:


III. Jesus’ Warning (Revelation 2:22–25)


IV. The Conquerors (Revelation 2:26–29)


Conclusion and Invitation

  1. Keep doing the good deeds we are already doing—but strive to do them better.
  2. Refuse to practice or tolerate the sins of Jezebel.
  3. Love each other enough to correct sin, never allowing it to become “acceptable.”
  4. Victory belongs to those who conquer through faithfulness to Christ.
  5. Jesus calls us today to repent, turn from compromise, and receive the Morning Star, eternal fellowship with Him.

“He who has an ear, let him hear what the Spirit says to the churches.” (Revelation 2:29)
