"Dear JW,
Can you please explain, using only the Bible,
1) Proof that Jesus began to reign in heaven in 1914 ?
2) How taking Blood Fractions is acceptable ?
3) Why only 144,000 go to heaven ?
Please only return when you have the Bible proof."
I think a simple little flyer like this for householders to give to JW's could make them wriggle, and you never know, even think.
