10 But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.
11 Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives
12 as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat

New International Version

1 Follow God’s example, therefore, as dearly loved children
2 and walk in the way of love, just as Christ loved us and gave himself up for us as a fragrant offering and sacrifice to God.
3 But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people.
4 Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving.
5 For of this you can be sure: No immoral, impure or greedy person—such a person is an idolater—has any inheritance in the kingdom of Christ and of God.
6 Let no one deceive you with empty words, for because of such things God’s wrath comes on those who are disobedient.
7 Therefore do not be partners with them.

New International Version
