Wow. (2Peter 1:3-11) talks about Making One's Calling and Election Sure, "His divine power has given us everything we need for life and godliness through our knowledge of him who called us by his own glory and goodness. Through these he has given us his very great and precious promises, so that through them you may participate in the divine nature and escape the corruption in the world caused by evil desires......" (vs.3-4)
(2Peter 1:12-21) talks about Prophecy of Scripture, "....We did not follow cleverly invented stories when we told you about the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty......And we have the word of the prophets made more certain, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. Above all, you must understand that no prophecy of Scripture came about by the prophet's own interpretation. For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit. (vs.16,19-21)
(2Peter 2) talks about False Teachers and Their Destruction, I could not pick out a few versus, one must take time and read it. :-)
(2Peter 3) talks about The Day of the Lord, "First of all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires......But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentence..... (vs3, 8 & 9)
Of course each chapter has more to say than what I highlighted and as I read each one I was encouraged, I hope it can encourage others as well.
Be Blessed and Have a Great Day!!! :-)
