"What steps are you going to take to keep your mind sound and your heart sober so that you don't gradually slide into the subtle mental delusion that this world is what really matters, and then lose your alien identity? If this fall you slowly show the signs of dabbling with the mind-altering pleasures of the world, who is going to be close enough to spot it? I urge you to consider that this is what small groups at Bethlehem are for. They are meant to combat the creeping, drunkening, mind-altering, deluding effects of this God-ignoring world. They are meant to be recurrent jolts of reality. Repeated sessions of reality therapy. They are meant to be bi-weekly sessions where the first stages of addiction to the world can be detected and lovingly confronted and remedied with the Word of God and the power of the Spirit." -John Piper
(from "How Aliens Keep the Identity of The Homeland" based on 1 Peter 1:1-2, 4:7-10).
