The fact is that in the stubbornness of your impenitent heart you are treasuring up against yourself anger on the day of Anger–the day when the righteousness of God's judgements will stand revealed.
Since all this is so, the Lord knows how to rescue godly men from temptation, and on the other hand how to keep the unrighteous under punishment in readiness for the Day of Judgement,
But the present heavens and the present earth are, by the command of the same God, kept stored up, reserved for fire in preparation for a day of judgement and of destruction for the ungodly.
