Only this morning, I heard that news report. The report said, a woman. Persons were surprised. 'A Woman!'
A reporter said, that of all the school shootings... some 4 thousand, I think, only four of those shooters were women.
Anyway, I commented that this might have been an attack on persons professing belief in God, and we must expect more to come, as the world moves more toward atheism, and away from God.
People are becoming more and more angry, and they are becoming more hateful of those who defend God, because they are tired of hearing about God.
The demonic forces are behind it, as Revelation 12:12 is under fulfillment.
