2 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”
The reason we read and study the Word.  The Bible isn’t like any other book which you can read and set aside.  It is the living Word of God.  Our souls and spirits need it like our bodies need food and water.  We read it over and over to bring what it says inside us.

3-7  “…there shall come in the last days scoffers…Where is the promise of His coming…this they willingly are ignorant of…by the word of God the heavens were of old…reserved unto fire against the day of judgment…”
The longer we’re on this earth, the more scoffers will mock God and His promises.  But they can’t get away from the truth.  As Peter said, they willfully forget.  I’m always amazed that those who would take what someone wrote 100 years ago as proof of what happened then, won’t believe the Bible, even though the things in it have been proven over and over.  They don’t care for the facts, they want their own desires.  Unfortunately for them, the truth won’t change.  Judgment is coming.

8  “…one day is with the Lord as a thousand years, and a thousand years as one day”
Many try to use this as some formula for interpreting the passing of time in the scripture.  Peter meant it as no such thing.  From the context it is obvious he was only showing that God is timeless, He is not bound by time.  He is the creator and sustainer of it.  He sees the past and the future as clearly as today.

9  “The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.”
One of my favorite verses.  The reason we are still here.  And evidence of God’s great love for ALL mankind.  Also a good starting point for any discussion of predestination or limited atonement.

10  “…the day of the Lord will come as a thief in the night…heavens shall pass away…elements shall melt with fervent heat…earth also and the works that are therein shall be burned up.”
From the text, it’s hard to know exactly what Peter is referring to.  On the one hand, thief in the night denotes a surprise or something we weren’t expecting.  This sounds like the coming of the Lord at the rapture of the family of God.  The heavens and the earth passing away speaks of the very end of recorded time after the Millennial Reign, though I don’t see how that would be unexpected.  Commentary suggests that day of the Lord is not a single point, but the whole series of events of His coming beginning with the Rapture, which will be sudden and unknown or unexpected, and concluding with the earth and heavens being reformed.  That makes sense as it appears Peter was mentioning aspects of all of it.

11  “Seeing then that all these things shall be dissolved, what manner of persons ought ye to be…”
We know what is coming, so how should we act?  Not only in holy conduct and godliness for ourselves, but also with a sense of urgency for those who don’t know Christ, since the start of the end will come as a thief in the night.

13  “Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.”
Light at the end of the tunnel.  What a day that will be.

15  “…the longsuffering of our Lord is salvation…”
Hard to wait, and we get impatient.  But for every one who will believe, given the time, it will be worth it.

16  “…in which are some things hard to be understood…”
I’m encouraged that even Peter found some of Paul’s writing hard to understand.

16  “…which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction”
Apparently people have always tried to make the scripture say what they wanted.

I hope you enjoy reading and studying His word.  May it accomplish what He desires.  Please feel free to comment or post questions.  Thanks for reading!
