Your question was about something I already addressed. Which you don't understand so that is why I answered you with that question.
Once again, here is the part of the post....reread and see if you don't understand my thoughts on it.
I think, the same can be said for the scripture that states we were chosen in him before the foundation. Scripture also states that the lamb was slain before the beginning of the world. We know this was not actually the case, so it must be speaking of God's foreknowledge. God made a plan for salvation, in that he sent his only begotten Son so that whosoever believes in him should not perish. If we accept and believe in him then we are elected in him. If not then we will surely perish. Put simply God has the foresight and foreknowledge to know who will believe, obey, and accept his gift and plan for salvation and who will not. He doesn't make people accept it and he doesn't reject anyone. It is the persons choice, yet God knows the beginning from the end. He is the alpha and omega.
