This is a positive proof of the righteous judgment of God [a sign of His fair verdict], so that you will be considered worthy of His kingdom, for which indeed you are suffering.

Then the lawless one [the Antichrist] will be revealed and the Lord Jesus will slay him with the breath of His mouth and bring him to an end by the appearance of His coming.

It was to this end that He called you through our gospel [the good news of Jesus’ death, burial, and resurrection], so that you may obtain and share in the glory of our Lord Jesus Christ.
