For Christians, deception about the return of Jesus Christ is dangerous and unproductive; nonetheless, Paul describes in broad brushstrokes what that day will look like. It will be a bumpy ride, but the Christian will not be caught off-guard but make it through to the end, as long as he endures and keeps firm in the Lord Jesus Christ and the Word of God. Here is my sermon on this from 2 Thessalonians 2:1-12 (c.f. Daniel 7:1-10). Other passages that are helpful to accompany this are Luke 17 and Matthew 24.
