Where exactly did I say that? All I said was that God will make certain that everyone who is seeking him will find him, and that sometimes this occurs through visions. The problem is that most people don't seek God and aren't interested in the truth. They're merely interested in doing what they want to do, and not really interested in finding God. People constantly demonstrate this time and time again when they ask others to prove God exists, but yet they don't actually make any effort to find the truth themselves.
When I wanted to find out the truth about God I didn't go ask other people to tell me the answer, I went searching for it myself. I was raised as Christian, tho I left the church for 4 years prior, but I didn't go directly to pro-Christian sources because I wanted to hear arguments for and against different religions. I didn't let anyone's opinion influence me and stuck to what the facts said. I spent time examining historical evidence, arguments for and against many religions, and reading different religious books. I spent 6, 8, even 10 hours a day doing research, and I read nearly the entire Bible in a week. I did this for at least a month before coming to the conclusion that Christianity was the truth about God, though I wasn't totally convinced and kept asking God to tell me what the truth was. Finally I did receive a vision in which Jesus said something along the lines of "You're on the right track, but you need to make a bigger room for me.". At the time I wasn't quite sure exactly what it meant, but he said I was headed in the right direction so I kept going.
My point is that people don't find God because they aren't looking for him. What reason God have to show himself to you if you are neither seeking or even trying to do what's right? God isn't like people, he knows he's supreme and has no need to prove himself to anyone, so the "show yourself or else" mentality wont attract any attention from him.
