“Please silence your pagers and cell phones as we prepare to worship the living God. We welcome you to use your phones, readers, or other digital devices to follow along in God’s Word, but we warn you that this is the worst possible time to send texts, check email, or bomb angry birds. God demands and deserves our full attention, and he destroyed Nadab and Abihu for offering “strange fire” during worship. So use your kindle fire at your own risk.”Somehow I don't think that would go over very well!
BTW, the Nadab and Abihu reference is from Leviticus 9 & 10.
