If JWs read their Bible, they should know that God blesses non-JWs............
(Matthew 5:44-45) 44
However, I say to YOU: Continue to love YOUR enemies and to pray for those persecuting YOU; 45
that YOU may prove yourselves sons of YOUR Father who is in the heavens, since he makes his sun rise upon wicked people and good and makes it rain upon righteous people and unrighteous.
(Acts 14:14-17) 14
However, when the apostles Bar´na·bas and Paul heard of it, they ripped their outer garments and leaped out into the crowd, crying out 15
and saying: "Men, why are YOU doing these things? We also are humans having the same infirmities as YOU do, and are declaring the good news to YOU, for YOU to turn from these vain things to the living God, who made the heaven and the earth and the sea and all the things in them. 16
In the past generations he permitted all the nations to go on in their ways, 17
although, indeed, he did not leave himself without witness in that he did good, giving YOU rains from heaven and fruitful seasons, filling YOUR hearts to the full with food and good cheer."
(Luke 6:35) 35
To the contrary, continue to love YOUR enemies and to do good and to lend [without interest], not hoping for anything back; and YOUR reward will be great, and YOU will be sons of the Most High, because he is kind toward the unthankful and wicked.
