If God knows all why did he let Satan into/stay in the garden of Eden?

Or "the serpent" if you don't think it was Satan.

Either way, free will only applied to humans, which means he could have prevented the whole "sin/misery/death" thing by just tossing the reptile out before it ever met Eve.

God knew it would happen, and he just walked off to play Minecraft or whatever, knowing there was a serpent who would Rube-Goldberg humanity into misery.

God didn't make us to be "sims" or "robots"
gave us freewill
Had Adam exercised his dominion, he could have kicked out Satan forever. But he didn't.
Satan went after Eve first, she was deceived. Adam wasn't.

Had God not had that, then we would have been no better than robots.

God knows what he s doing. Why question God?

Free will? Really? "Believe in me or you will burn for eternity" does not sound much like free will to me.

For a test… THEY WERE IN PARADISE WITH ONE RULE AND STILL BLEW IT! Hard to believe huh? NOW WE HAVE NINE RULES… THEY SHOULD HAVE LISTENED TO THEIR MAKER.

"Either way, free will only applied to humans"

Where'd that rule come from? Why wouldn't the angels/devil have had free will?

HE HAD HIS REASONS, I WOULD SAY YOU COULD ASK HIM WHEN YOU GET TO HEAVEN BUT SINCE YOU WON'T BE THERE OH WELL

First of all if any god was real this forum would of shut down long a go! If god is supposed to be so magical why do we need police, and why do they need powerful weapons if god is so magical! It is only a man made up word to make wealth for the pushers or spreaders of the lies! If you can't see that then you are blind!

The fact of the matter, NO, God has to test all of us, that is why it is written in God word the bible only, NO man comes to the father but through the son Jesus Christ, he did all the work before the foundation of the world, that is why he is called the lamb slain before the foundation of the world. God tests everyone, God even tested God Jesus Christ for 40 days and 40 nights by Satan the man of sin. But God Jesus Christ passed the test, where Adam an Eve failed the test, Abraham passed the test, but Solomon the wises kings failed God test, that is why Solomon dynasty was destroyed by God Jesus Christ, because he was not a true child of God, and only a true child of God will do the will of God and the will of God is to be obedient to God word the bible only, nothing else.
