An omniscient being has no need for "experiments", wouldn't be unable to foresee the threat of "Satan subverting that purpose", etc, and has no need for fall-back plans, making it up as He goes, playing it by ear, etc, or any of the other concepts that apply to non-omniscient beings, since God would already KNOW what was going to happen.
If God was entirely omniscient and prescient, he would have destroyed Satan before he could cause damage to his plans, don't you think? Because a God of love that was simultaneously omniscient and prescient would know beforehand that Satan's agenda would cause mankind to get in all sorts of trouble and suffering, causing also humans to stop believing in a God of love. What kind of God would bring reproach upon his own name?
