Why don Kingdom Halls have windows?
That’s like asking why donuts have holes. What difference does it make? If you are imagining that there is some sinister reason, there’s not. Actually, many kingdom halls do have windows. But, it seems that the preferred architectural design is for kingdom halls without windows. Probably, the main reason is that glass windows are a tempting target for vandals.
Generally, a Kingdom Hall is built without windows only in areas which tend toward hate crimes and vandalism against houses of worship. Sadly, it seems that the questioner is from such an area, and perhaps even more sad that such religious intolerance occurs worldwide. http://jw-media.org/newsroom/human_right… Perhaps these anti-Witness bigots fail to understand that their vandalism and persecution actually work to help prove that Jehovah’s Witnesses are true Christians. (2 Timothy 4:3-5) For there will be a period of time when they will not put up with the healthful teaching, but, in accord with their own desires, they will accumulate teachers for themselves to have their ears tickled; and they will turn their ears away from the truth, whereas they will be turned aside to false stories. You, though, keep your senses in all things, suffer evil, do the work of an evangelizer, fully accomplish your ministry. Lea
