I also watched this video some time ago, and it explains how I've thought of the way people interpret god and use the belief if god to their advantage. It is also rather explanatory of why the religous people are so disgusted with atheists. I feel some of this has even been shown in this discussion
Pardon the bad post quotation, my iPad isn't ideal for this.
I watched the video, and it's a decent thought experiment, but far from airtight.
First of all, it proposes that God is introduced to an atheist solely through being talked to by a theist. Untrue, many have come to faith in Christ through their own, private study of scriptures. Some have, like Paul the Apostle, been actually confronted by God himself, an idea the video seemed to dismiss as impossible.
The video also takes the nonexistence of God as the most logical thing. One must be convinced that God exists. Also not true for many people. But the video was only about atheists, so we won't call that a mistake.
The video also made God impersonal. How can you reject some one that isn't there? According to the Bible, Jesus stands at the door and knocks. If some one is trying to get your attention and you purposefully ignore them, how is that not rejecting that person?
So why doesn't an omnipotent God just show up and settle all doubt? Because it wouldn't. People who looked Jesus in the eye, listened to his teachings, saw him raise Lazurus from the dead, how many signs did they need? They wanted to kill him.
Tell me, if a ginormous neon sign fell from heaven that lit up and said I'm God, I'm here! Would you and all mankind suddenly believe? Nope,not even all the ones that saw it fall with their own eyes. And 100 years from now when the sign was all rusted and gone, people would deny it was ever there to begin with.
I used to think there was a way to let all men see, to get everyone to believe, but there's not.
One thing the video got right- the truth exists independent of our feelings about it. Based on what I know about God, I feel compelled to believe in Him. The Bible agrees with the video maker in that regard as well, no one can come into the kingdom of God unless the Holy Spirit draws them. The problem isn't that the Holy Spirit doesn't draw, we just refuse to acknowledge it for what it is.
The video also purported that God only knows what we know, because He is actually us. So how does prophecy work? Oh, you don't believe in that? How convenient for you. But there are several hundred prophesies in the Old Testament that Jesus fulfilled, many of which wre outside of His control, such as where He was born or how He was killed. But that sign isn't enough either, maybe because it happened too long ago.
You want modern signs and miracles? God healed me of asthma when I was in 6th grade. He healed my son of ichthyosis. He healed a woman in my church who had a curved spine from a car accident. He healed another woman who was going deaf, completely restoring her hearing. But it isn't enough, it will all be discounted or explained away.
I'm sorry if I sound frustrated, but from my perspective Jesus parades Himself in front of us every day and we still reject Hom.
