The main theme of 2 Peter is exposing and combating false teaching; however, he never mentions the specific heresy that is being taught. At the heart of all wrong doctrine is misinterpreting and even twisting Scripture, which Peter alludes to in 2 Peter 2. Not only does Peter expose the false teachings, but also the evildoing of the teachers. The New Testament writers often equate false doctrine with evil works. Those who have a wrong belief system will reveal the error of their ways through a sinful lifestyle. Overall, Peter’s second letter is doctrinal in nature but is careful to provide practical outlets to defend the authority of Scripture and live a life of faithfulness to God’s ways.
