In Jeffrey Johnson's sermon "The Rules of Engagement," based on 1 Corinthians 14:26-40, he addresses the theme of orderly worship and the importance of corporate church attendance. Johnson begins by humorously recounting a story about a pastor reluctant to attend church, underscoring how even committed Christians can occasionally feel disinclined to gather for worship. However, he stresses that this should not become a habit or excuse to neglect church.

The core message of the sermon revolves around Paul's correction to the Corinthian church's disorderly practices, particularly regarding the misuse of spiritual gifts like tongues and prophecy. The Corinthian church had turned their services into chaotic, unstructured events where multiple people spoke at once without interpretation or discernment, which hindered worship and learning. Paul, in chapters 12 through 14, teaches that these gifts must be exercised in order and with a focus on corporate edification, not individual experiences.

Johnson makes a larger application of this passage to modern churchgoers, outlining four reasons Christians should regularly attend church:

1. Attendance is assumed: Paul doesn't explicitly command church attendance because it is taken for granted that Christians will gather for corporate worship.

2. To serve and edify one another: Church is not just for personal benefit but for building up the body of Christ. Each member's gifts and presence contribute to the growth and encouragement of the community.

3. To learn and be encouraged: Church is a place for teaching, learning, and mutual encouragement. Proper order in worship allows for everyone to understand and grow in their faith.

4. To submit to God’s order: The structure of the church is designed by God, and all members, including spiritual leaders and women, are called to submit to the roles and order He has established.

Johnson emphasizes that church attendance is not merely about fulfilling a duty but about corporate worship, learning, serving, and submitting to God’s design. He concludes by stating that the church is essential for spiritual growth and sanctification, and it offers a foretaste of heaven through the love and unity shared among believers.
