Peter wanted to rouse the complacent believers who had listened to the false teachers and believed that because salvation is not based on good deeds, they could live any way they wanted.
If you truly belong to the Lord, Peter wrote, your hard work will prove it.
If you’re not working to develop the qualities listed in 2 Peter 1:5-7, maybe you don’t belong to him.
If you are the Lord’s-and your hard work backs up your claim to be chosen by God (“called and chosen”)-you will never be led astray by the lure of false teaching or glamorous sin.
2 Peter 1:10 So, dear brothers and sisters, work hard to prove that you really are among those God has called and chosen. Do these things, and you will never fall away.
