Religion can't be destroyed. It's an idea and ideas can't be destroyed. Places where religion is declining is more often that not common in places that are communist or are becoming more communist. American and much of Europe are slowly becoming communist with some of the rules they've made. We all know communists have had dislike of religion, not because they disagree with it, but because people will be loyal to the government only, not their deities. Why do you think many of them in Russia and China took the time to destroy temples and churches? For fun? There was a reason behind that.
In Scripture there is a distinction between true or genuine religion and fake-myth religion.- James 1:27
Even among those professing to be Christian - see Matthew chapter 7 - MANY will prove to be false.
When Jerusalem became apostate in the year 70 God used the Roman armies as His arm of the law to go against Jerusalem.
So, it should Not surprise anyone that God would once again use the political/military forces against those proving false to Him.
We are nearing the coming ' time of separation ' on earth - Matthew 25 vs 31,32,37 - when those judged as righteous ones can continue to live on earth right into the start of Jesus coming millennium-long day of governing over earth.
So, what will be destroyed are all the false religious groups - Isaiah 11 vs 3,4; Rev. 19 vs 11,15
The words from Jesus' mouth will be as a sharp executioner's sword to eliminate those who would bring ruin to earth.
- Rev. 11:18 B. Bring ruin either literal or morally.
