Why you guys always miss this very, very important part whenever I say this is beyond me, but it is always, always because "WE DON'T KNOW". Are any of you understanding this yet? Because it changes the map for us a lot, and I do mean "A LOT".
Jesus believed in determinism, and the fact that all is/was predestined/predetermined, and in fact, he was the first to discover/know this.
I see, your a universalist. Well. I hate to tell you, you're wrong, and are not basing your ideas on the truth of scripture and what Jesus believed in/taught.
Your reasoning is faulty, re-think it again.
It's not because God couldn't get the job done, but only because temporary evil people in every single creation when each is made or each is created are always needed/necessary for (or during) the time/times when they are still fallen temporarily still, but are no longer necessary when they are not. They were always meant to be like that, and cannot change their fates from God's perspective, but from our perspective, they always still can, but that is only because we do not know what God already knows and already caused from God's perspective of knowing all (things) already, etc. From God's perspective, and under determinism, they could never change it, like ever, in any of the creations, which is why it is eternal, etc.
If we knew everything God knows, then there probably wouldn't ever be much of a reason for us to ever do or ever try to change anything, (individual/collective fates, etc), but because we don't, and never do, there always is a very, very good reason to always try to do that, or try to do these things always (or try to change/alter either individual or collective fates always), etc. Like I said, the map is a lot, lot different for us, etc.
God Bless.
