"I know your works, that you are neither cold nor hot. I could wish you were cold or hot. So then, because you are lukewarm, and neither cold nor hot, I will vomit you out of my mouth." (Rev. 3:15-16)

In the book, "The Screwtape Letters" by C. S. Lewis, a devil briefs his demon nephew, Wormwood, in the subtleties and techniques of tempting people. Through the letters, the devil says that the objective is not to make people wicked but to make them indifferent. Satan cautions Wormwood that he must keep the patient comfortable at all costs. If he should start thinking about anything of importance, encourage him to think about his luncheon plans and whether or not it could cause indigestion. The devil then gives this instruction to his nephew: 'I, the devil, will always see to it that there are bad people. Your job, my dear Wormwood, is to provide me with people who do not care.'" (From Brett Blair)

Let us not be indifferent or lukewarm, but concerned, zealous, and active in the work of the Lord.
