This sounds like you want God to be a parent who plays tennis with their child but lets the child win every game until they’re 21, lest their fragile self-esteem be hurt by losing.
Nope.
That child won’t in any way grow or develop as a tennis player, much less as a person able to cope with both good and bad things happening, unless they learn
a) that they CAN lose and
b) that inevitably they sometimes WILL lose a game or two, but that it’s not the end of the world because they can use it constructively to learn and develop greater skills, and can become a good player in spite of occasionally losing.
God has the ability (because he has infinite power) to do both. He could let “the child win every game until they’re 21”, and the child would still grow and develop as a tennis player (hey, I did it with my neice and nephew and board games, and God is supposed to be more powerful than me - the trick is to let them win, but challenge them at every stage).
A close run game and advice will allow you to show how some thing will work and some will not. Usually what I do is say why the move I am doing will not work and why the move they do will.
See God, like any good parent, wants His children to learn and grow and develop their potential, and excel as human beings. In other words to become great as saints and people.
Which involves a learning process, and also involves the risk of hurt and failure.
God has the power and knowledge to be able to just instill us with this knowledge and not have it affect our free will or anything.
In the face of an all powerful God, your arguemnts are not valid.
The only way you can make your arguments valid is if you put limits on God, but then He would not be the christian God if you did that. God is more than just a “parent”, He is a parent that can do anyhting He knows, and He knows everything.
Job 42:2: " know that You can do all things,
And that no purpose of Yours can be thwarted. "
"No purpose of Yours can be thwarted": This means that no matter what else occurs, the purpose that God sets out can not be changed unless He wants it to be changed. So if God wanted there to be no sin, but still allow free will to choose it, He can do that!
This means that the only reason that anything occurs is because God wills it to be that way. Thus, if there is suffering in the world, the
ONLY reason it is there is because God wants us to suffer, and for
no other reason.
A loving God would not want us to suffer if He could prevent it. As the only reason for suffering is because God wants us to suffer, then we can conclude that either God does not exist (and suffering has some other cause/reason), or God is a monster who wants us, mere mortals completely under his dominance (Job 42:2 remember), to suffer.
He doesn’t want them to be mediocre - not doing anything wrong, but being only moderately good and obedient, and that only by default rather than by choice.
Again, only if you limit God ability to do things. If God is all powerful then God can make us do what He wants, and still have free will.
The often-used metaphor of gold or silver being refined to it utmost purity by being put through fire is apt here - the fire in our case being the trials and tribulations and risks attached to the possibility and reality of sin.
However, God being all powerful could sort the Gold or Silver atom by atom (the technology to do this actually exists now, made by finite humans - or are we more powerful than God), or even just create it pure form the start and prevent any contamination from occuring at all.
The reason that people have a problem with this is because we humans are not very good at understading infinity.
As an example:
Can God create a rock so heavy He could not lift it?
If God has infinite power, then He must be able to make a rock that is too heavy for Him to lift, but also if He has infinite power He can lift any rock no matter how heavy it is.
For us, this seems like a contradiction, but to a being of unlimited ability it is not. God can create a rock thatis too heavy for Him to lift, but then He just lifts it.
So can God eliminate our ability to sin, but still allow us to choose to sin?
Yes, even finite power beings can solve this.
How I would do it is allow people to choose to sin, but not have thier actions effect anyone else. IF I had the power, just create a temporary reality to put them in with “faked” entities that they sin against. In computer games this could be done by creating an instanced area as the user tries tocommit one of the sins.
If a mere mortal can think up a solution to the problem of being allowed to sin but not allowing them to sin, then a being with infinite power and infinite knowledge could do the same.
Only if you let God not be infinite in power or knowledge (but then could He be called a God then, certainbly not the christian God at any rate), can you impose such limits on Him (remember any limit imposed means that God is no longer infinite).
