> For if our heart condemn us, God is greater than our heart, and knows all things (1 John 3:20).
> Known to God from eternity are all his works (Acts 15:18).
> The eyes of the LORD are in every place, keeping watch on the evil and the good (Proverbs 15:3).
The idea of omniscience leads to paradoxes like the one above. Can you know what it is to be non omniscient and be omniscient.
I think God can choose to understand and know what He wants to know. If he chooses to forget sin, He can. Meaning the strict definition of omniscience would not apply.
I'm no theologian or philosopher so there is a good chance I'm simply missing something or don't understand these words.
If the axis of your response is going to be this, then I suggest we only continue speaking about the Bible on the level of Koine Greek for the New Testament and Hebrew for the Old.
Since you want to be maximally true to the words. As do I.
