What I took from the sermon is that Satan realized that killing Christians naturally in the arena wouldn’t work because they would just go to Heaven ( which would defeat the very purpose).
So Satan learned that killing people spiritually (in the church) would be much better so eventually when they die they would go to Hell.
We need to stay with the Word so we don’t get deceived. Well, that’s what stood out to me. Thanks for reading have a good rest of your day.
