Peter wants us to enjoy the certainty of our salvation. He wants us to be so firmly established in God that any temptation or false teaching cannot shake us. Peter helps us in chapter 1 by reminding us about God’s precious and very great promises. In Chapter 2, he assures us that God knows how to rescue his children from trials, also false teachers. The Lord knows how to keep unrighteous under punishment until the day of judgment. Peter doesn’t just mean God knows how to do it. It means He has done it in the past; He will do it in the future.
