I have a couple of questions regarding your premise that you stated
Quote
By this definition could God not made His choice of election based on who Hew knew would accept??
.

On what basis does God know this? Is He looking into the future or does He know our disposition by the way He made us.

Regarding the former, if he know by looking into the future is He responsible for bringing two Christians together for marriage or is it just a random occurrence. IOW, He foreknows how the randomness of men will play out, but He does not take an active part in it. But, I think you would say that God played a big part in bringing the two together, based on His knowing who will accept. I just don't see how God is providential in all (or most) things
except salvation.

If the latter, then that is really not a choice on our part.
