This sermon examines Jesus' letter to the church of Ephesus from Revelation 2:1-7, addressing the critical issue of abandoning one's first love for Christ. The message emphasizes that Christianity is fundamentally about affection for Christ, not merely activity or duty. Pastor Jeff challenges believers to examine whether their devotion has turned into mere duty, whether their obedience has lost its affection, and whether their faith has become a job instead of a joy.
