The Christians in Laodicea (Revelation 3:14-22) had become like the lukewarm, dirty water imported from neighboring cities. Hot water is relaxing. Cold water is refreshing. Tepid is terrible.
What happened? Because of their great wealth they felt self-sufficient. They could purchase nice houses, clothing and medicine. What else did they need? Riches can blind us to our need for God. In reality they were naked and blind.
Jesus asks the church to invite him back. To repent and be zealous again.
Is your passion for Jesus lagging? Do you feel self-sufficient? Ask God to open your eyes and see your need for Him.
