Nobody is ready for what will come soon, in a few decades IMO - Worldwide Islamic Supremacy (WIS).
Believers in Christ will be gone - in fact WIS will be launched by the departure of the saints from the earth (the great “catching up” (1 Thess. 4:17) AKA the rapture of the church).
Even Muslims will be shocked because the spirit of antichrist will be in full swing driving them to do things they would not ordinarily do as the “Twelfth Imam” (the beast) rises to power.
That will be Satan’s time, used by God to judge the world that has rejected the Christ who died for them, and to bring in Christ’s 1000 year rulership as the Prince of Peace.
The entire 20th Century and the 21st Century so far has been Satan's time.
