In our study of 2 Peter chapter three, we are told of how we are to live our lives based on what the apostle has reminded us of in the previous two chapters. He urged us to grow in faith and knowledge so that we will not be deceived by false prophets. Now, we will see that with knowledge comes responsibility.
"Dear friends, this is now my second letter to you. I have written both of them as reminders to stimulate you to wholesome thinking." NIV translation
Peter wrote these letters to believers that were scattered throughout the Roman provinces of Asia Minor. As we see here, his goal was not to reach the lost but to remind the believers of what they already had and to get them to grow and sink their roots into the Word of God. The "wholesome thinking" speaks of sincere minds or those that are genuine believers in Jesus Christ as the Son of God, Lord, and Savior. This is in contrast to those that he talked about in chapter two who are destined for judgment.
"I want you to recall the words spoken in the past by the holy prophets and the command given by our Lord and Savior through your apostles." NIV translation
Peter shows us here that it is important to know the words of the Old Testament prophets as well as the teachings of the apostles. Both of these sources were chosen by God to share the knowledge of Him with us and the rest of the world. There are many today that do not study the Old Testament as they say the law does not apply to us. They are right in that we are not under law but grace but it is the foundation of our faith.
The words of the prophets help us to understand the need for Christ as well as what we have in Christ.
"First of all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires." NIV translation
We see from this verse the importance of knowing that the false prophets will come and to be prepared for them. That preparation is studying the Word in order to grow (the second purpose of this website). The last days that he refers to is the time that we are in now. The Old Testament predicted the first coming of Jesus Christ while the gospels proclaimed that He had come and would come again. These last days are the waiting for that return.
