Laodicea was a city with two sources of water. From the north an aqueduct brought water from hot springs that cooled down on the way. From the south-east a channel brought cool mountain water that heated up on the way. As a result it was a place of lukewarm water. For John, writing the Book of Revelation, this was a fitting picture of the tepid, half-hearted character of the faith of the Laodicean church. Apathy, indifference, complacency are not the way of faith. The call is to love wholeheartedly and to live with full commitment.
