It seems to me that the first thing you need to do is prove to yourself that God exists and then that Jesus Christ is his Son and then get to know them so that you have faith that They love you and that they can and will do what they say. For me it was a very long journey How can you build your faith? Paul tells us in Hebrews 11:1 1 Now faith is the substance of things hoped for, the evidence of things not seen. You must seek out the evidence of things not seen. Like building a case of circumstantial evidence in a court of law. The case will be built on the sum of circumstantial evidence not any single proof. You said in another post: "If the spiritual interacts with the earthly in any way, it should leave traces of it's activity. For instance, if Jesus himself were to show up in Tokyo, where there would be plenty of eyewitnesses to see it, that would leave proof." Well, this did happen, just not in Tokyo during your lifetime to the present. So you must search the history books for the historicity of Jesus Christ as well as evidence for the existence of the God that was his Father. Was there really a man named Jesus Christ that was born in Bethlehem, Judea, who preached that he was the Son of God and was crucified for his efforts? Was there really a man named Pontius Pilate who was the Procurator of Judea, during this time period? The questions to be asked are endless. Why are our calendars (Gregorian calendar) reset at the birth of Christ? Were there really Twelve Apostles? What happened to them? You also said: "If God gives someone information, and that person had no possible way to access that information on their own, then that's proof as well (I.E. the location of buried treasure). Well. I ask you, where did the modern day country of Israel come from? Why were all of those Jews sent to the ovens by Hitler's Germany? Where did the term "Jew" come from? What was the Jewish diaspora? Who were the Twelve Tribes of Israel? Why are Ten of them lost? Was there really a King Solomon, a King David who ruled over a country called Israel around 1000BC? Why was their country divided in to 2 parts? Was their really a King Nebuchadnezar of Babylon? Was their really a King Daruis the Mede? Who was Cyrus the Great? Who was the prophet Daniel? Who was the prophet Samuel? What is in the Dead Sea Scrolls? I tell you if you find the answers to these you will find buried treasure.
