2 Peter 1:5 “for this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge…”
2 Peter 1:12 “Therefore I intend always to remind you of these qualities, though you know them and are established in the truth that you have…”
2 Peter 1:19 “And we have something more sure, the prophetic word, to which you will do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts..”
2 Peter 3:18 “But grow in the grace and knowledge of our Lord and Savior Jesus Christ.”
Peter’s primary solution for fending off false teaching was knowledge of good teaching; knowing how true doctrine sounds, feels, and manifest itself. The gospel is like “a lamp shining in dark places.” Knowing and holding fast to true doctrine will always be key for the Christian living in a world where God’s Word is continually attacked and tampered with. This is why knowledge is a reoccurring theme of Peter’s second inspired letter. In fact, the word “knowledge” appears sixteen times in these three short chapters. I’d add that a vague knowledge is not enough. We need to be deeply immersed in the waters of Scripture, not just tip-toeing around the shoreline. It is so critical that we love God’s word, cherish it, memorize it, and count it as more important than our daily food.
In other words, “The best offense is a good defense.”
