Sorry, my other response was a bit flippant. I believe with all my heart that God chose me and knew me. The Bible tells me so.
I can only look in reverse, however. From my side of the veil, I know it is true because of the choice I made.
It is ultimately irrelevant to talk about God’s election, other than as a theoretical curiosity, since we have absolutely no way to know other than by running a test from our side of the veil.
It is up to us to accept that choice. We make a choice as well.
