There are always consequences. To believe in something does not automatically make it true. If I believe I can step in front of a bus doing highway speeds without getting hurt, the laws of physics will not suspend themselves if I do so. Reality will quickly set in. It's important to note here that my window of opportunity to re-think my belief exists only before I step in front of the bus.
Similarly, if you are incorrect about the existence of God, and you die, that reality will quickly set in. If God exists, and many scientists believe this to be true, His laws will not be suspended either. Your choice will also be locked in at that moment.
If you research and understand this paradigm, it involves God creating us as free moral agents, with the ability to accept or reject Him. The rationale behind this is that love cannot be coerced. You cannot force someone to love you.
Suppose you were God. (Attempting to understand an infinite mind using our limited ones is extremely presumptuous, but for the sake of discussion, let's give it a shot.)
We understand, even in our minor way, the joy of creating something. Suppose you could create beings to hang out with. Like Sims, but with squishy bits. Yes, you could program them to want to spend time with you. In fact, you could program their every response. Or, you could do something much more exciting and satisfying, and give them free will. Of course, not everyone will want to hang out with you. However, the ones that do will be hanging out because they want to. They will also give you the only thing that you can't create, their love.
You likely wouldn't invite them to your house until they get things figured out. Your house is pretty nice and they would probably make a mess. Plus, it would seem pretty mean to eventually boot them out of paradise, just because they chose not to love you, right? Much better that they could 'opt in', rather than being cast out.
So, it might be a good idea to create somewhere they could be while they made this decision. Set them up with an amazing little world, equip them with a moral compass and then give them enquiring minds.
The next part is a bit tricky, you want to be there for them, to help them grow and fall in love with you. However, you can't just fix all their problems and give them everything they want. If you do, they will just follow you to make life easy, not because they love you. As painful as it will be, you will have to let them make their wrong decisions, experiencing the consequences of their actions, because that is the only way that they will learn.
You won't leave them in the dark, however. The very design of their world will point to you, (if they wish to acknowledge it). You will also personally go down there, taking their form, speaking their language and explain what you had in mind for them. You will offer them a clear view of the decision involved, if they desire to make it.
Then what? If they're not interested, if they decide they don't want to hang out with you, you must abide by their decision and give them what they asked for. Those are the consequences of free will.
In this petri dish we call earth, as a free moral agent, it is your choice to accept or reject God. My goal here is to urge you to make this an informed choice. If you do the research, you will realize that you do not have to put your intellect on the shelf in the process.
