Peter is not saying:
- time moves more quickly in the sky (relativity)
- God can't tell the difference between 1000 years and one day
- time does not exist in the sky (1000 years = 0)
Instead he's say:
- in terms of wait stress, time does exist for God but 365,000 days = 1 day;
He's saying that God has no more difficulty waiting 1000 years than we would waiting overnight. That is, God experiences time (because God lives in the sky, not beyond it) but never becomes impatient, taxed by time the way the people who live on the earth do. For us a 1000 years is not only beyond our personal patience, it is also beyond our life spans. And 1000 years is even a heck of a long time for a people to wait the fulfillment of a promise such as the one made to Abraham or in the prophets.
2Pe 3:9 The Lord is not slow about his promise, as some people
understand slowness, but is being patient with you. He does not
want anyone to perish, but wants everyone to repent.
So Peter is saying that God's patience is not challenged by plans that span generations. He's patient.
He goes on to say that his patience is motivated by a desire to give everyone an opportunity to repent:
2Pe 3:9 The Lord is not slow about his promise, as some people
understand slowness, but is being patient with you. He does not want
anyone to perish, but wants everyone to repent.
There is a saying, "If you can't do the time, don't do the crime". God is "the Kooler King" in that he can handle the time required to fulfill his plans. He has the patience:
2Pe 3:15 Think of our Lord's patience as facilitating salvation,
just as our dear brother Paul also wrote to you according to the
wisdom given him. 2Pe 3:15 Think of our Lord's patience as
facilitating salvation, just as our dear brother Paul also wrote to
you according to the wisdom given him. 2Pe 3:16 He speaks about this
subject in all his letters. Some things in them are hard to
understand, which ignorant and unstable people distort, leading to
their own destruction, as they do the rest of the Scriptures.
Peter describes God's patience as the virtue of being willing to put up with an objectionable situation for a long period of time to reach a good end:
2Pe 3:15 And account that the longsuffering of our Lord is
salvation; even as our beloved brother Paul also according to the
wisdom given unto him hath written unto you;
So what Peter is saying is that patience is a virtue and God has that virtue and so should the believer.
I should also add that James also describes God's longsuffering and then calls the believer to emulate his patience:
Jas_5:7 Be patient therefore, brethren, unto the coming of the
Lord. Behold, the husbandman waiteth for the precious fruit of the
earth, and hath long patience for it, until he receive the early and
latter rain. Jas_5:8 Be ye also patient; stablish your hearts:
for the coming of the Lord draweth nigh.
Of course as in many scriptural admonishment the notion that the arrival of the long awaited promise is finally at the doors is given which rings a bit hollow this late in the game:
Jas_5:8 Be ye also patient; stablish your hearts: for the coming of
the Lord draweth nigh.
Or is that his point?
