Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. (2 Thessalonians 2:1-4)
And many Western believers will be disillusioned when we realize more adversity and suppression and tribulation - even such as other believers are now enduring - rather than being delivered from such as expected, as if we are better than many other believers and those of the first century church.
And apparently many believers cannot tell the difference between small *t* tribulation that we all experience in our lives and capital *T* the Tribulation that is God’s dealing with Israel and judgment for sin on an unbelieving world.
