Where in the Scriptures does God ever say that He just foresees events?
God is omniscient, he knows all things.
It was you who quoted Scriptures about the Lord guiding our steps and knowing our plans; you also asked if I thought that God doesn't know the details. Now you're asking where it says that he does this. ??
For the manifestation of His glory.
The scenario I suggested does not glorify God.
To create a universe which is
very good, to say, "I need man to sin because I have already planned to send my Son to suffer for that sin", would be cruel - if not foolish. Why mess up something perfect so that your Son can go through rejection, torture and immense pain to put it right again?
If you heard of someone who took several days to create a masterpiece of art, making sure every detail was just right, and then throwing black paint over the whole thing, wouldn't you want to ask them why they had done that? And if they said, "so that I can publicly clean it all off again and restore it to how it was before I decided to throw the paint over it", wouldn't you at least question their sanity?
I don't know about you, but those actions would not inspire me to think, "this artist is amazing, I must become one of his fans."
Fair? If you want God to be fair, He could have left Adam and his posterity (including you and me) to perish eternally without a Savior. This would have been perfectly "fair" and just. God is under no obligation to the creature. The fact that God sent His Son to save sinners is an undeserving privilege on His part.
I know it is.
What I asked was, if God determined, or predestined, that Adam would sin and Adam did sin; he was doing what God wanted and following God's plan.
So why punish him?
You quoted 1 Peter 1:19-20, but then contradicted it after. How was Jesus chosen from the foundation of the world, if that not includes before Adam's creation?
You didn't read the bit before; God provided a Saviour before we knew we needed one.
God sees all things. He is the Alpha and the Omega, the beginning and the end. Before he even created them, he knew that human beings would sin against, and disobey him. So he had a plan for that before it happened. Prevenient grace; grace that came bore sin. Before we call, God answers; before we sin, God has a solution.
I wasn't contradicting the verse I quoted; of course Jesus was chosen before Adam's sin.
I am saying that God KNEW that Adam was going to sin. He did not
make Adam sin, nor plan that he should do so; he just knew that it was going to happen.
The prophets knew that the Israelites would be taken into exile for that sin and they knew that God would restore them again afterwards. They did not cause the people to sin, and they did not make the Babylonians invade the nation and destroy the temple; they just knew that it was going to happen.
They knew Jesus was going to come, live, minister and die. They didn't make it happen; they just foretold that it would. Jesus knew that Judas would betray him and Peter would deny him. He didn't make them do those things; he just knew that they would.
God knew that Adam would sin and mess up his perfect world, so he already had a plan for when he did. Like you said, Jesus was not God's back up plan.
But that is far from saying that God caused Adam to sin, or needed him to do so.
