He challenged the believers to become more mature in their faith by adding to it specific Christians virtues, thereby becoming effective and productive in their knowledge of Jesus Christ (2 Peter 1:5-9). The Old and New Testament writers were set forth as their authority for their faith (2 Peter 1:12-21, 3:2, 3:15-16). Peter desired they become strong in their faith to withstand the false teachers that had crept in and adversely affected the churches.
Yeye alitoa changamoto kwa waumini wawe wakomavu zaidi katika imani yao kwa kuiongezea wema/maadili maalum ya kikristo, na hivyo kuwa wenye nguvu/wanaofaa na zalishi katika ufahamu wao wa Yesu Kristo (2 Petro 1: 5-9). Waandishi wa Agano la Kale na Agano Jipya waliwekwa mbele kama mamlaka yao kwa imani yao (2 Petro 1: 12-21, 3: 2, 3: 15-16). Petro alitamani wawe na nguvu katika imani yao kuhimili walimu wa uongo ambao walikuwa wamejipenyesha na kuathiri makanisa vibaya.
