SALVATION 2 Peter 3:13-15

But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells. So then, dear friends, since you are looking forward to this, make every effort to be found spotless, blameless and at peace with him. Bear 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. 

But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells 
Isaiah 65:17  "See, I will create new heavens and a new earth. The former things will not be remembered, nor will they come to mind."
Isaiah 66:22  "As the new heavens and the new earth that I make will endure before me," declares the LORD, "so will your name and descendants endure."
Revelation 21:1  Then I saw "a new heaven and a new earth," for the first heaven and the first earth had passed away, and there was no longer any sea."

make every effort to be found spotless, blameless and at peace with him 
1 Thessalonians 3:13  May he strengthen your hearts so that you will be blameless and holy in the presence of our God and Father when our Lord Jesus comes with all his holy ones.

Bear in mind that our Lord's patience 
Romans 2:4  Or do you show contempt for the riches of his kindness, forbearance and patience, not realizing that God's kindness is intended to lead you to repentance?

means salvation 
2 Peter 3:9  The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.

just as our dear brother Paul also wrote you with the wisdom that God gave him 
Ephesians 3:2-6  Surely you have heard about the administration of God's grace that was given to me for you, that is, the mystery made known to me by revelation, as I have already written briefly. In reading this, then, you will be able to understand my insight into the mystery of Christ, which was not made known to people in other generations as it has now been revealed by the Spirit to God's holy apostles and prophets. This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Christ Jesus.
