Re: “God knows the beginning from the end.”
-The only way for God to have knowledge of the beginning to end, is to already have been there. Meaning He can time travel. According to biblical teaching, God is all knowing from the beginning of time to the end of time , and yet was unable to prevent the outcome of past events, that being the attempted overthrow of His reign in Heaven by Lucifer and his rebellious cohorts.
And for the there to be evil existing in heaven once, wouldn't logic also follow that it will be repeated. Rarely are any events singular by natural laws. If an object falls to earth once, it will fall every time. Using sound reason and logic, He cannot be all powerful, if he was unable to prevent future events, that being the pride and vanity of his most fair and beautiful angel Lucifer. Have you ever considered how illogical that is?
We only know about attributes of God from what He has revealed of Himself. If He didn’t reveal it, we would not be able to find out.
What you say about time travel would put God “inside” his creation and subject to the laws of it. Now, we’re told by contemporary scientists that the attribute of “time” has to exist along with matter and the dimensionality of the universe and it’s existence. Time doesn’t exist as an entity in and of itself, but only in conjunction with matter and space. If ,after and space don’t exist, neither does time. If matter and space exist, then “time” must exist right along with it, at that moment.
God existed prior to creation which means he existed prior to time and is this not subject to it or part of it. At a certain point, God created everything seen and unseen (the universe and it’s existence, if you will).
So “time travel” doesn’t fit in this particular way that God has revealed himself.
As far as preventing things from happening. The Bible makes it clear that God had a plan from before creation - before anything was there. That plan included the fact that Lucifer fell, other angels with him, and sin entered creation by way of Adam and Eve’s actions.
You’re assuming that the proper choice of action would be to prevent it from happening. I can assure you, in a very “human way” (and God is much higher in his ways than humans) - I let bad things happen, knowing that they are going to, because I see it as the better course of action.
For example, there was my little boy (I call him mine, even though I’m more taking care of him than anything) ... who was playing around with the car doors in the driveway. He likes doing that, but from watching him I knew that he was going to slam his fingers in the door. I could see it coming. Now prior to that, over a period of time, I did take the effort to show him to not have his fingers in the way, but that didn’t sink in. So, I finally just watched, knowing what was going to happen, and it did. He came running and crying, and I comforted him - and then warned him again, later, about it.
But since then, I notice he doesn’t get his fingers in the way and he has not slammed his fingers in the door since then, and it’s been a long time.
I chose to let the bad thing happen, in order for a better thing later on. That happens a lot with people. It can certainly be the case with a God who created the universe, all things seem and unseen.
And then, you say God cannot be all powerful if he cannot prevent future events. You’ve got am assumption there that he wants to,prevent the things you think he should. That’s the mistake understanding God.
We all were created with a certain degree of free will - not unlimited, but within certain boundaries. Within those boundaries that God has set up, we do have our choices (again, not unlimited, but within limits). One of those area is that we can choose to abide with God and who he is - or - we can totally reject him and have nothing to do with him. God has set that up as something you can freely choose, within your overall boundary of free will.
Therefore much of what you see is God allowing what he has chosen to allow for people’s own free will. It’s not an inability to do anything, it’s a freedom he has granted. It won’t last forever, as this freedom is not totally unlimited, and there is a “day of accounting” for your choice - but you do have it in the meantime.
Your choice of having nothing to do with God will be honored and he will remove himself from you and all that is good and upright - and you will be left - in the end - in the lake of fire, with your own free will choice.
