If a thousand years for us is but a day for God, in God's eyes this should make the earth 7 + 6 = 13 days old, am I right ?
Well, in reading that verse (actually it's 2) in fullness we begin to get the broader meaning more fully:
8 But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. 9 The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.
You begin to get the sense of the wording -- that any amount of time is for God any other amount of time He chooses.
So, a billion years are like an hour. Or a second is like a million years....
If He chooses....
But it does help suggest something profound about His words when He says "day"......
Such as:
"but of the tree of the knowledge of good and evil you shall not eat, for
in the day that you eat of it you shall surely die.”
Of course Adam lived another 900 years....
But 900 years is like a day to God....
Or a 33 year human lifetime is a 'day' also:
14 “The day will come, says the LORD, when I will do for Israel and Judah all the good things I have promised them. 15 “In those days and at that time I will raise up a righteous descendant from King David's line. He will do what is just and right throughout the land."
Genesis chapter 1 says nothing at all about how much mere mortal time passed.
We also have nothing at all in Genesis chapters 2 and 3 about how much mortal time passed on Earth while Adam and Eve dwelled in the timeless paradise of the Garden of Eden with the eternal Tree of Life -- the same tree that will be in heaven we read in the last chapter of the bible:
Eden Restored
22 Then the angel showed me the river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb 2 down the middle of the great street of the city. On each side of the river stood the
tree of life, bearing twelve crops of fruit, yielding its fruit every month. And the leaves of the tree are for the healing of the nations. 3 No longer will there be any curse. The throne of God and of the Lamb will be in the city, and his servants will serve him. 4 They will see his face, and his name will be on their foreheads. 5 There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever.
How long is a 'day' in heaven then?
The Earth is a mere 4.55 billion years old in mere mortal time, which is passing away, and will cease to exist.....
It's a time duration that means little or nothing really..,..
It's God's time that matters, not ours.
