And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works. --Revelation 2:23Jesus and the grim reaper are getting together to kill a bunch of babies. Then afterwards they'll pile up the kidneys (reins) and hearts so that Jesus can sort through them.
The bible is full of atrocities, in both testaments. It doesn't take much research to find them. Of course, most christians I know would say that this verse is symbolic. Symbolic or not, it paints a terrible mental image of Jesus.
