I was on My Facebook and someone said this to me:
“i think the scripture they quote does a great job disproving open theism all by itself.”
You mean this verse?
Psalm 139:4, 16 state, “Before a word is on my tongue you know it completely, O LORD…All the days ordained for me were written in your book before one of them came to be.”
First of all, God knows the words we are going to speak before we speak them because He knows our hearts and minds. Jesus knew what was in their hearts even before they spoke at all. That part of the verse does not mean that God foreknows from eternity all of the future as an absolute certainty.
Second of all, all the days ordained does not mean what occurs within those days but the number of those days. And the fact remains, God can shorten the days of the wicked as proverbs says and God can also add days to your life like He did with Hezekieh. So the future is open as God is able to change it by adding or subtracting the days of your life.
The fact that all the days of your life are written in the book does not mean that everything that occurs on those days is eternally settled nor that the book cannot be edited and re-written. Just as the Book of Life can be edited as people can be blotted out of it.
So that verse that they quote does not do “a great job disproving open theism.”
