This lesson focuses on two of those churches, the first and the last. The church at Ephesus is commended for its activity, perseverance and doctrinal purity. But theological correctness and hard work are not enough to gain our Lord's unqualified praise. Jesus scolded this church for forsaking her first love. I believe both.
Love is a package.
Go back to the basics. Try worship, public and private. Your light goes out. In other words, your witness suffers. This could be the fate of the church at Laodicea.
