<p>3:2 <i>That you should remember the words which were spoken before by the holy prophets and the commandments of the Lord and Saviour through your apostles</i>- AV: &quot;Of us the apostles&quot;. The things written in Peter's letters were therefore a reminder of what had been spoken by the New Testament prophets, and what Peter and the apostles had taught all the thousands of converts who were baptized at Pentecost. There was clearly follow up teaching in addition to the address recorded in Acts 2. The &quot;prophets&quot; would refer to the group of Christians who spoke on that day as inspired prophets, fulfilling Joel's prophecy of prophets being raised up.</p><p>The letters of Peter urge his readers to &ldquo;be mindful of the words which were spoken before&rdquo;. Yet this is evidently alluding to the frequent references to the disciples being slow to &ldquo;remember&rdquo; s.w. &ldquo;mindful&rdquo; the words which their Lord had &ldquo;spoken before&rdquo; (Lk. 24:6,8; Jn. 2:17,22; 12:16). Indeed, the same word is used about Peter &lsquo;remembering&rsquo; s.w. &ldquo;be mindful&rdquo; all too late, the words which his Lord had &ldquo;spoken before&rdquo; to him (Mt. 26:75). So Peter was aware that his readers knew that he had not &lsquo;remembered&rsquo; the words his Lord had &ldquo;spoken before&rdquo; to <i>him</i>- and yet, knowing that, he exhorts his readers to &lsquo;remember&rsquo; or &lsquo;be mindful&rsquo; s.w. of words which had been previously spoken. His readers likely had memorized the Gospels by heart. And yet Peter asks them to learn from his mistake, not to be as slow to remember as the disciples had been, and he especially. This is the basis of powerful exhortation- a repentant life, not an appearance of sinlessness.&nbsp;</p>
