Well, God is God whether it is only in a digital world or elsewhere. He is God everywhere.
I was not offended, I just wanted to reply.
Have a nice day.
1- God is not busy with other things, He always has time for everyone. He says that nothing makes Him busy or unable to hear the prayers of a human.
2- Just because someone makes a prayer does not mean that God has to answer it immediately. The delay in answering the prayer is part of the "lesson" that humans are taught. Patience yields more rewards than hastiness. Humans were created hasty, they like things to be done quickly, but to God, He makes it a lesson to teach humans patience through answering their prayers in phases/stages.
3-4- God cannot be compelled to answer. If a human continues to call on to God, asking Him to speak to them or "show them a sign" as though the whole world is not enough of a sign to them, then that is a problem. Any dream you would have is God's way of speaking to you. You have to remember that some people do not dream at all. It is not only a gift from God, but it is the sign you are asking for. Him not "showing you a sign" does not mean that you have done something bad and you need to fix it, it is that you continue to ask for a sign while ignoring the other signs you already see. God's "signs" are everywhere. Just show gratitude to them, that's all.
5- Do not ask God to talk to you saying "it's so quiet here".
6- God knew the letters you sent before you even sent them. In fact, He knew that you wanted to write the letters, so He let you do that from start to finish. What did you get out of it? The lesson that you learned?
7- God is real, whether you like it or not. You have been sending the letters before you even wrote them, He allowed you to write them down, and allowed you to post about them, and allowed you to make a "game" out of them. What was your purpose? Did you want to show people your letters? Did you want to portray God in a certain light? Did you only want to ask the final question "are you real?"
You can speak to God everyday without the need to post about it or show people what you told God. He keeps all your secrets and He shelters you, He is your refuge when you're crying out alone in your room. He keeps bad things from happening to you on a daily basis.
You should speak to Him with acknowledgement rather than with demands and doubts. Acknowledge His gifts to you and to your parents.
He is always there, always present and always listening to you. He is all powerful and all knowledgeable, all hearing and all seeing. You don't have to ask whether or not He is - it would cause His displeasure.
Acknowledge it, do not cause doubt about it.
