God calls people to repent and separate themselves from the kingdom of this world so that they will not be caught up in its judgement.
God will bring judgment upon those who pridefully oppose him.
God will one day display his glory by pouring out his wrath on his enemies.
The earth will be reaped and both the redeemed and the lost will face judgement.
Christians are encouraged to endure to the end by seeing the salvation of the redeemed and the judgement of the wicked.
