For example a good first step would be that next time you encounter an argument for God in this forum, actually make an honest effort, try to understand the argument, and try to spot the strengths and weaknesses of the argument. Try to identify the premises of the argument, and then try to determine if you find them more plausibly true than wrong.
Already done decades ago. That's what critical thinker does. The cases for gods are the same handful of arguments over and again, all of them already refuted. There's nothing left to consider unless somebody comes up with a new argument.
The OP's so-called proof of God was, "Allow yourself to suspend your skepticism momentarily and ask God (however you understand God) to reveal Himself to you." Didn't work. Another proof refuted.
Incidentally, the critical thinker never suspends skepticism. He may suspend disbelief to test an idea as I did with Christianity in the early seventies, but he should never suspend skepticism. Critical thinking is our only defense against accumulating false beliefs, and it begins with skepticism, or the insistence that an idea not be accepted as correct on faith or authority. If suspending skepticism, which isn't really possible for an experienced critical thinker, is the only possible way to believe an idea, then that is not an idea he wants in his knowledge set. As soon as one informs him that he has to suspend skepticism to believe something, he loses interest in whatever it is that can only be believed this way.
I think that the believer and the rational skeptic have a different understanding of what this phrase means. Your suggested suspending skepticism. Why would the critical thinker ever do that? That is the fundamental principle of critical thought - that no idea should be accepted before investigating the quality and quantity of supporting evidence, and not believing more than is supported, always tentatively, always ready to adjust ones estimate of the likeliness of a proposition being correct up or down as more supporting or contradicting evidence arises. Once one has seen the merit to this approach, he has no reason to decide what is true about the world any other way. Open-mindedness never suspends skepticism and critical evaluation when evaluating a claim.
What the critical thinker means when he says he will consider a proposition open-mindedly is that he will consider the idea and any attendant evidence and argument dispassionately, that is, with a willingness to be convinced by a compelling argument. Rejecting a flawed argument is not closed-mindedness as the theist often implies. He presents his case and its flawed arguments, which are consistently rejected, and writes that off to closed-mindedness. It's as if he is trying to tell me that 2 + 2 = 5, I evaluate his argument and reject it, he presents his error thirty more times, it is never accepted because critical thinking rejects it, he tells me that I need to relax my standards for belief if I am to believe what he does, and that if I don't, I'm stubborn and closed-minded.
Marine biologists refer to plankton - the living things unable to choose their path in the water, going where the currents go. A less well-known word is the nekton, the living things that swim, walk, sidle - whatever - to get to where they want to be. They choose their direction. I liken these two ways of thinking - faith-based and critical thinking - and the people that engage in them to these concepts. If you're a faith-based thinker, your mind goes where the ideas that you have accepted uncritically take you. It needn't be religious thought. If you believe that an election was stolen not because you examined the evidence properly and found the claim well-supported, but because somebody else wants you to believe it and you don't have the skills t defend yourself from that kind of manipulation. That's being intellectual plankton.
It doesn't happen to the skilled critical thinker. He has charted a path toward verifiably correct ideas, and cannot be whisked off by the current carrying the plankton. And this seems to distress the plankton, who seem to resent seeing the nekton charting it own course rather than floating off with them.
