2 Peter 3:8-18
8But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. 9The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance.

10But 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 in it will be laid bare.

11Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives 12as 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. 13But in keeping with his promise we are looking forward to a new heaven and a new earth, the home of righteousness.

14So then, dear friends, since you are looking forward to this, make every effort to be found spotless, blameless and at peace with him. 15Bear in mind that our Lord’s patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him. 16He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction.

17Therefore, dear friends, since you already know this, be on your guard so that you may not be carried away by the error of lawless men and fall from your secure position. 18But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be glory both now and forever! Amen.

1 John 2:1-5
1My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense—Jesus Christ, the Righteous One. 2He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.

3We know that we have come to know him if we obey his commands. 4The man who says, “I know him,” but does not do what he commands is a liar, and the truth is not in him. 5But if anyone obeys his word, God’s love is truly made complete in him. This is how we know we are in him: 6Whoever claims to live in him must walk as Jesus did.
