If we believe those days are coming, it's time to get out of our comfort zone and preach the gospel to all peoples. The Master is coming and will settle all accounts.
We must be “wise as serpents; harmless as doves”. If I recall my Bible correctly, the Antichrist is supposed to come on the scene before the day of the Lord. So, we must be aware of the times and the Scriptures; study the Scriptures, rightly dividing the word of truth. The 24th Chapter of Matthew is a good passage to study on the return of Christ, with warnings - informing us that His return will be like the lightning flashing from the east to the west, and sudden with us being caught up to meet Him in the air.
