Peter already used the language of escape in 2 Peter 1:4 as a descriptor of the divine act of salvation. This would imply that he is referring specifically to new converts, people who have only recently turned from idols to serve the living and true God (1 Thessalonians 1:9).1
18 For, speaking loud boasts of folly, they entice by sensual passions of the flesh those who are barely escaping from those who live in error.
