In the Old Testament we see examples where God prevents the sun from moving, fire/hail coming from the sky to kill enemies, and whole attacking armies are instantly blinded to save praying people. For example, when Judea was under threat by the Assyrians, and Hezekiah prayed, the text says an angel flew over the Assyrian army and killed 185,000 soldiers instantly. (2 Kings 19)
Why has God stopped doing that? Why not send an angel to instantly kill all of the Nazi soldiers who were rounding up the Jews or attacking Europe? (Surely millions were praying just as eagerly as Hezekiah) Why not instantly blind all the rapists who are currently attacking children?
These are all the kinds of things that were reported in the past, so why have they stopped now?
