deceive the nations

Satan will be released from his prison and will come out to deceive the nations , that is Gog and Magog, to gather them for  battle. Their number is like the sand of the sea and they marched up over the broad Earth and

surrounded the camp of the Saints and the beloved city,

but Fire came down from heaven and consumed them; and the devil who had deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophets were; and they will be tormented day and night, for ever and ever.

Revelation ch 20

 Before Christ second coming the church must pass through a final trial that will shake the faith of many believers. The persecution that accompanies her pilgrimage on Earth will unveil the “mystery of iniquity” in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth.  Catechism 675

offering men an apparent solution to their problems at the price of apostasy from the truth

I believe we are now in this time of apostasy.
