Peter never said that in God’s “prophetic scheme”, one day is a thousand years and a thousand years is one day.
Peter simply remarked on how what may seem to men like a long delay in fulfilling a promise is not that long to God.
There is no justification for making a biblical numerology formula that in prophecy one day means a thousand years.
“A thousand years” is just a figure of speech meaning a long time. Like in Psalm 50:10 it says:
For every beast of the forest is mine, and the cattle upon a thousand hills.
This “thousand hills” is a figure of speech meaning a lot of hills, or better, on all hills.
Note that this verse below says one day is as a thousand years, not one day equals a thousand years.
I Peter 3:8
But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
Of course, AsceticX, I would not want to convince you against your will. But I will say that God has as one of the most important doctrines in his whole Bible that incorporates this formula, the "day of the Lord." This is a prophetic theme appearing in the scriptures a total of 30 times over a period of some 800 years. It appears in this format, "day of the Lord" in the writings of 12 Bible authors and in 15 books (some authors wrote more than one book, i. e. Jeremiah/lamentations). In every instance, without exception, it is in the future tense. Prophets in both testaments spoke of it. In it's initial application it begins as a dark day with no light. It is a day of vengeance of God upon angels and men. It is a time of the absence of God upon the earth. It is time of his wrath and the purging of sin by purging sinners from the earth. It is the beginning of the 7th one thousand year days of God on the earth and it is his sabbath when the morning breaks. It follows the pattern of a Jewish day, the evening and the morning is the 7th day.
There is a broader prophetic application to this day where more information is given, often time, what the day will be like after the wrath is over. This information is determined by the phase "in that day."
Let me give you an example of that;
Isaiah 2:12
For the
day of the Lord of hosts shall be upon every one that is proud and lofty, and upon every one that is lifted up; and he shall be brought low:
Isaiah 2:20
In
that day a man shall cast his idols of silver, and his idols of gold, which they made each one for himself to worship, to the moles and to the bats;
Isaiah 5:30
And in
that day they shall roar against them like the roaring of the sea: and if one look unto the land, behold darkness and sorrow, and the light is darkened in the heavens thereof.
That happens during the night.
Here is what happens during the day.
Isa 11:1 And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots: (this is Jesus Christ)
2 And the spirit of the Lord shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the Lord;
3 And shall make him of quick understanding in the fear of the Lord: and he shall not judge after the sight of his eyes, neither reprove after the hearing of his ears:
4 But with righteousness shall he judge the poor, and reprove with equity for the meek of the earth: and he shall smite the earth: with the rod of his mouth, and
with the breath of his lips shall he slay the wicked.
This must happen if he is to reign the world in righteousness.
5 And righteousness shall be the girdle of his loins, and faithfulness the girdle of his reins.
6 The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them.
7 And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox.
8 And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice' den.
9 They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the Lord, as the waters cover the sea.
10 And
in that day there shall be a root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and his rest shall be glorious.
11 And
it shall come to pass in that day, that the Lord shall set his hand again the second time to recover the remnant of his people, which shall be left, from Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath, and from the islands of the sea.
12 And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.
13 The envy also of Ephraim shall depart, and the adversaries of Judah shall be cut off: Ephraim shall not envy Judah, and Judah shall not vex Ephraim.
14 But they shall fly upon the shoulders of the Philistines toward the west; they shall spoil them of the east together: they shall lay their hand upon Edom and Moab; and the children of Ammon shall obey them.
15 And the Lord shall utterly destroy the tongue of the Egyptian sea; and with his mighty wind shall he shake his hand over the river, and shall smite it in the seven streams, and make men go over dryshod.
16 And there shall be an highway for the remnant of his people, which shall be left, from Assyria; like as it was to Israel in the day that he came up out of the land of Egypt.
Only God would know these things are out there in the future. They for sure have never happened in the past. Give me some advice from your view of scripture. Should we believe the words that are written in Isa 11 or are you wanting those you teach to see these words as figurative only and without any kind of literal meaning?
The day of the Lord comes. It is the same day as the day of wrath from the Lord. It is finally present tense.
Re 6:12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
13 And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17 For the great day of his wrath is come; and who shall be able to stand?
It is 1260 days long.
If we do not accept God's formula for a day we will never have sound doctrine on the end times.
