If God had, yes that would be the case.
Adam had free will, God knew he would fall, God did not have to ordain that to happen, but because that happened God had to have a plan to redeem mankind. Do you agree Adam had free will?
Define "free will".
Also, God planned the Cross before
Adam fell, not afterwards. It was not a response to anything, since God could easily have prevented Adam's fall.
Adam had free will, where is the proof God determined Adam to disobey his commandment? Are you saying God wants Adam to break his own commandments? He wants Adam to sin? Satan wants that, so he can murder Gods creation, cause seperation, not God.
You are again conflating God's preceptive and determinative wills.
If God gives Adam free will to choose, God sist back and has to let him,
God is in charge, not man. God's word says that God works all things according to the counsel of his own will. He has not hamstrung himself, in any way.
So because God did not jump in and stop it, knowing full well what would happen, he predetermined it, he allowed it to happen, is that correct?
Since God knows what would happen, in any given set of circumstances, his action and inaction are both determinative, bringing about what he intends to be.
So God issues a commandment, because he has to, but is hoping they disobey it, which they did. That is your take on the two wills, yes? You see I do understand it.
Oh, good grief!
How about God gives them free will, knows they will break his commandment, but doesn't want them to and then has to deal with all the fall out, meaning the chaos that will come after. Maybe God knew it would happen, but couldn't prevent it because of God giving man free will. If you have a son or daughter, do you lock them in a room for their whole life in case they do something wrong, like take drugs? Or do you give them freedom and give them advice and hope they will listen?
If you have a son or daughter, and see that child running towards a cliff, do you:
A) Sit there wringing your hands helplessly, because you can't countermand the child's "free will"?
B) Rush out and grab the child, so that a disaster does not happen?
Adam and Eve didn't listen.
The problem you have is once you say God has two wills and one will is opposed to the other, especially when we are dealing with sin, if God commands man to obey, but Gods other will is for him not to, if man disobeys Gods commandment, Gods will is being thwarted by his own determinsitic will. God has become divided within himself.
You still don't understand that determining what will happen is in a different category from telling man what he ought to do.
What does Jesus say about a divided house? Mark 3:24-25
The house is not divided at all, but you don't grasp why.
The bible is very simple to understand, but Calvinism introduces such complexities, that things like two wills have to be introduced into scripture to make Calvinism seem plausible, but it becomes very exposed.
Some things in the Bible are easy to understand, but others are hard, as even the apostle Peter stated.
God cannot be divided against himself, his will was for Adam and Eve to keep his commandment, they had free will, they didn't keep it, it's that simple. God commands man to repent and believe in the gospel, some will, many won't it's that simple. No need for two wills.
Check what the Bible says about God bringing his purposes to pass. It's not nearly as simplistic as you make out.
