Peter reminds us God is able to His fulfill his promises, patiently (2 Peter 3)

In 2 Peter 3 we see God as  Lord, Savior, Creator, and Patient:

 - 2 Peter 3:9, Lord isn't slow, but patient toward you
 - 2 Peter 3:13, His promise, new heaven and earth - eternal life with God
2 Peter 1:3-4 we may become partakers of the divine nature (again taste and see Psalm 34)

We see a connection to Revelation 16:8-9
The fourth bowl - on the sun, scorches everyone with its fire, they refuse to repent and glorify God (Deuteronomy 28:22 scorching heat and drought until perish; 2 Peter 3:7 heaven and earth are reserved for fire)
(9) they cursed the name of God, refused to repent and glorify him
 - I just listened to "Eternity: Your Choice by Robert Morris" and he had an insight that "glory" is what you're famous for and used famous people in sports, etc... to show the point. When Moses asked to see God's glory, it was like he was asking - what are you famous for?

Then Moses said, “Now show me your glory.”
And the Lord said, “I will cause all my goodness to pass in front of you, and I will proclaim my name, the Lord, in your presence. I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. Exodus 33:18-19 NIV

Outline of 2 Peter 3
A) Purpose
1-2) beloved, writing to stir up a sincere mind, remember words spoken prophets, the commandment of the Lord and Savior

B) Current mockers forget God's historical word and power evidenced in their own argument of "beginnings and death" - see Genesis 1-3
 3-4) last days mockers, follow own lusts, "where promise of His coming?", death only no change since the creation
5-6) they forget by word of God heavens existed, earth formed, water form, destroyed by flood

C) Day of Lord will come suddenly, judgment will be swift
7) by His word present heavens, earth reserved for fire, the day of Judgement, destruction of ungodly men
8-9) day is like thousand years, Lord not slow about Promise, patient toward you wishing all to come to repentance
10) Day of Lord, like a thief - heavens pass away, elements destroyed earth and it's workds burned up

Applications: glorify God with our good lives, found in Christ Jesus
 - 11-12) we in holy conduct and godliness, looking for and hastening coming day of God
 - 13) according to His promise, looking for new heaven and a new earth in which righteousness dwells
 - 14) be diligent to be found by Him in peace, spotless and blameless
 - 15-16) regard patience of our Lord as salvation as Paul wrote (The good news of Jesus Christ and it's impact on everyone (Romans))
Warnings: Guard against error, don't fall away from Jesus Christ
17) be on your guard, not carried away by the error of unprincipled men and fall from your own steadfastness

Bottom line:
18) grow in the grace and knowledge of our Lord and Savior Jesus Christ to Him be the glory now and to the day of eternity.
