9 The Lord is not being slow in doing what he promised—the way some people understand slowness. But God is being patient with you. He doesn’t want anyone to be lost. He wants everyone to change their ways and stop sinning.
10 But the day when the Lord comes again will surprise everyone like the coming of a thief. The sky will disappear with a loud noise. Everything in the sky will be destroyed with fire. And the earth and everything in it will be burned up.
11 Everything will be destroyed in this way. So what kind of people should you be? Your lives should be holy and devoted to God.
12 You should be looking forward to the day of God, wanting more than anything else for it to come soon. When it comes, the sky will be destroyed with fire, and everything in the sky will melt with heat.
13 But God made a promise to us. And we are waiting for what he promised—a new sky and a new earth. That will be the place where goodness lives.
14 Dear friends, we are waiting for this to happen. So try as hard as you can to be without sin and without fault. Try to be at peace with God.
15 Remember that we are saved because our Lord is patient. Our dear brother Paul told you that same thing when he wrote to you with the wisdom that God gave him.
