Oh dear! That's what tends to happen when I rely on memory.1) I think you were referring to Isaiah 46:10,
Yes, but 'the beginning,' from which God declares the end, is older than ancient.and his words there are:
Isaiah 46:10 Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
At least in this verse you quote it's "declaring" not "decreeing" and it's "from ancient times" not "eternity".
1Ch 4:21 The sons of Shelah the son of Judah were, Er the father of Lecah, and Laadah the father of Mareshah, and the families of the house of them that wrought fine linen, of the house of Ashbea, 1Ch 4:22 And Jokim, and the men of Chozeba, and Joash, and Saraph, who had the dominion in Moab, and Jashubilehem. And these are ancient things.
We would agree that Saraph did not have the dominion in Moab from "eternity".
I rather thought I had. All God's decrees were issued in eternity.. This has to do with the simplicity and unchanging nature of God. "For I am the LORD, I do not change.". And Jesus Christ is 'the same yesterday, today and forever.' If He was the Son of God in Psalm 2, He was the Son of God in eternity.Also, you haven't dealt with the expression this day. There are no "this day"s in eternity past.
The great puritan John Owen wrote: '"Today" being spoken of God, of him who is eternal, to whom all time is so present as that nothing is properly yesterday nor today, does not denote necessarily such a proportion of time as is intimated; but it is expressive of an act eternally present, nor past, nor future.'
In Colossians 1:13-18, we have a variety of things pronounced concerning 'the Son of [the Father's] love': Among these is the fact that the Son is the firstborn over all creation, that He created all things in heaven and on earth, visible and invisible, and that He is before all things. Also, according to Hebrews 1:2, the Son made the worlds.
But with reference to the subject of the thread, I think we are in agreement.
