Did you know Peter read Paul’s Epistles? 
I think he did.
2 Peter 3:16. 
Well, let’s start at verse 14 for the fun of it. 

¹⁴ Therefore, beloved, looking forward to these things, be diligent to be found by Him in peace, without spot and blameless; ¹⁵ and consider that the longsuffering of our Lord is salvation—as also our beloved brother Paul, according to the wisdom given to him, has written to you, ¹⁶ as also in all his epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures.  source 

And look at that Peter calls his readers, beloved. I remember in some recent studies I was comforted and encouraged at the depth (what I saw in the Text) of love Paul had for his people. And I think as I study Peter more I will find he had great love too. 

Our beloved brother Paul.
Wow.

According to the wisdom given to him, he wrote to you. 

And then verse 16. as also in all his epistles, speaking in them of things, . . .

Peter read Paul’s Epistles. 

I like that!

One more thing. Did you know the word PEACE appears 397 times in the NKJV?
