2 Thessalonians 1:6-Those Who Afflict Christians Will Fall Into The Hands Of God In Judgment

2 Thess

6 Since it is a righteous thing with God to repay affliction to those who afflict you (WEB)

The word righteous means an act that is right and good. God is a righteous judge who will punish those that sinned against Him by sentencing them to eternal darkness where there will be wailing and gnashing of teeth. They are the people who brought calamity to God’s children. The world [the devil’s kingdom] preaches tolerance, but their actions demonstrate hatred [satanic aggression] towards those who preach righteousness in Jesus Christ. 

All evil [word and deed] done here on earth will be judged by Jesus Christ on Judgment Day.
