Wave energy, Dark energy, and Potential energy are all immaterial. Yet we can clearly demonstrate their existence, directly, indirectly, and objectively. Also, these energies can be easily falsified. So being immaterial is no excuse to finding evidence to confirm God's existence.
No, immateriality alone is not the reason we cannot prove that God exists. The reason is because God does not want us to be able to prove He exists, and since God is Omnipotent, God calls the shots.
If a God had, in any way, interacted with our 4 dimensional reality, there would be some evidence of that interaction. There isn't. And, I believe there can't be, without completely destroying all of the natural laws of physics.
God could interact with this world without affecting the laws of physics. For example, God could communicate to our minds and cause us to take a course of action. Of course there is no way to prove that. Nothing God does can ever be proven, but that does not mean God does not do anything; we just cannot state it as a fact, and that is why it is a belief.
I find it rather silly when Christians go on about what God is "doing" in their lives, as if they could ever know that God was involved in whatever happened... I coined the phrase "naive believer syndrome" several years ago on a Baha'i forum and they got up in arms. Believers like to think they know what God is doing but that is so naive. We can believe that God did something in our life but we can never know it.
Saying that I believe that God exists because I believe that a Messenger of God exists, does not evidence either.
I do not believe God exists because a Messenger of God exists; rather I believe that the Messenger of God is the
evidence that God exists. God simply exists and would exist even if there were no Messengers. Of course there would be no way to know that God exists if God never sent Messengers, which is one reason God sends them.
Convincing myself to believe that something exists, that I can't demonstrate exists, just because others believe exists, is even worse than delusional. It is just gullible.
I agree. You should never believe that something exists just because other people believe it exists. That is the worst possible reason to believe in God. Baha'u'llah said that.
What is this way to prove to myself that God exists, since no one else can prove it for me("There is a way to prove to yourself that God exists..")? Never mind, I feel that it will be just another vacuous dangling participle, that promises something but will in the end deliver nothing.
In principle, it means that it has to come from within you, something you discovered yourself, not someone else's truth. If it does not ring true for you you should not accept it as true.
I am not God, so I do not know why it is so much more difficult for some people than for others to believe in God, and there might be
reasons why it is not God's intention that everyone believes in Him.
Baha'u'llah wrote that those who make efforts will surely be guided. Motivation is very important in anything we do, it is what drives us, so if someone is not motivated they are not going to make that effort. For many decades I had no motivation so I was not guided. I still believed God existed but it meant nothing to me.
