II Peter 3: 1-2.
This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance:
That ye may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour:
Peter refers to his first epistle as well as this second one that he is writing to the Christians in Asia. His purpose, clearly stated, is to stimulate their thinking by reminding them of the words of the prophets, the other apostles, and of the Lord, Himself, concerning the dangers always lurking, trying to persuade them that their faith is vain.
There really is nothing new under the sun, is there? Since the beginning, Satan has worked hard to deceive us and to bend the truth. Sometimes he succeeds. Consider Eve. The Genesis account tells us that she was deceived (Gen. 3:13; I Tim. 2:14). She was persuaded by lies and promises of being just like God.
Our best defense against Satan’s lies is the Word of God. When we are completely familiar with truth, we are far less likely to fall into deceptive traps that are shrouded with a thin layer of truth. I have used the example before of how new tellers at a bank are trained to recognize counterfeit money. They learn to recognize the false by being thoroughly exposed to the real thing. When we are diligent in reading and studying God’s Word, we are far less likely to be deceived by the perversion of His Word.
Peter says here that he wants to stimulate their “pure minds” with reminders of God’s truth. This is exactly the reason I started this blog over ten years ago, and have been writing ever since. There is no way to exhaust the truth of God’s Word. Studying the Bible in order to teach it is, for me, one of the best ways to truly learn and understand it.
Why did Peter emphasize “pure” minds? It is because we do have the old sin nature in us that would lead us to believe the cleverly disguised lies of Satan. The best way to keep that purity of mind is to faithfully be in His Word. Just as we need daily food and water to stay physically healthy, so our minds need daily feeding on the riches of the Word of God.
