There is a further explanation in Rom. 9:13-23, especially v. 18 and 19.
"So then he has mercy on whom He desires, and He hardens whom He desires. You will say to me then, 'Why does He still find fault? For who resists His will?'"
It did not work when Adam pointed the blame back to God for his sin, "the woman whom Thou gavest me...".
It will not work for us to say "Lord, you made me this way."
No biggie either way. I think it comes down to the Lord being the Lord of time and seeing the end from the beginning and the beginning from the end.
I don't disagree. I would add that in addition to seeing everything before it has even transpired, He is the creator of all and is Sovereign over it. We are blessed to be a part of His plan and to Glorify Him.
It will not work for us to say "Lord, you made me this way."
I agree. A pastor made a great comment to me when he said, "I'm always amazed by people who think that they will come up for judgement at the White Throne and argue with God."
My question about predestination vs free will in different eras is just a topic to see if we can learn more and understand more.
