How does Satan deceive the whole world today?
Through testing and proving all things, Satan deceives the whole world through things like Islam, Judaism and Christianity.
That is Revelation 12,13,14 on display on a spiritual level that most won’t or can’t see.
That’s different than what Babylon teaches because Babylon can’t see how the enemy works.
Especially because the enemy has had a legal right to meddle and even lead Islam, Judaism and especially Christianity.
You mention age of Grace and I was blessed to see Revelation going on this very day, but not in a way that will be perceived naturally.
What does that mean to one who sees the last 2,000 years as swine years?
It would simply be prophecy fulfilling itself while people are waiting for things to happen.
In any way similar to dog years?
