Yes, they will be stopped However, it will look like we are outnumbered and outgunned. Most people are asleep or on the broad path and wide gate to destruction. Good thing with God is that numbers do not control Him.
We are being called to wake up and walk with God. We are not the cults of Islam and Marxism focused in their trinity of hate, lies and death. We serve God because we reveal love, truth and life. God will sort it all out.
We just gotta have faith.
There is a building revival taking place in the earth, as the advance of the gospel has been accelerating in the last decade. We know that there will be a Great Harvest, and then — right in the middle of this burgeoning revival — up pops the Antichrist (II Thess. 2:8), and False Prophet to sow Great Deception (II Thess. 2:9-11), which results in a sudden Great Apostasy. In II Thessalonians 2:3 we see Paul set the revelation of the man of sin on equal footing with this apostasy; neither event will be done in a closet, nor will there be any mistaking them for anything else when they take place.
In that hour, faith will certainly be crucial, but the testimony of Paul to the Thessalonians (II Thess. 2:10) is that those who are perishing are those who do not receive the love of the Truth so as to be saved. The synthesis there is that many will have their preconceived time lines totally destroyed by the actual sequence of events, and it will require that these people recognize the Hand of The LORD, by faith abandon their demolished ideas, and cling more than ever to the Truth of the Bible. Revelation is, after all, a chronology. Yes, it is interspersed with “parenthetical” passages that make it a bit difficult to sort out, but it is a chronology nonetheless; it’s not that cryptic. Seals, Trumpets, and Bowls; Oh, my!
Sadly, there will be those who, when things shake out totally different from what they thought would happen, will take offense at God instead of apprehending faith, will not press in to lay hold of the Truth, and so will perish.
