Why can't god just show himself.
Let me tell you a story.
One time, a man was walking on a beach with Jesus and he looked back over his life, which had been lived entirely on that beach, so his footprints were all there in the sand and I guess the tide never came in and there wasn't much wind because the footprints were still there and he was like 70 years old.
So anyway, the guy turns to Jesus, and he's like, "Jesus, thanks for meeting me here. My first question, obviously, is about these footprints and not who really killed JFK or something interesting."
And Jesus said, "Right on."
So the man says, "Jesus, I notice two sets of footprints in the sand and the second set seems to be coming from you. So instead of asking how I didn't notice you walking with me these past 70 years, I would like to zero in on the places where there are only one set of footprints. I notice that those times correspond to the most difficult periods in my life because this is not an actual beach but instead is a metaphor."
And Jesus said, "How is it a metaphor? A metaphor for what?"
And the man said, "For sand." And Jesus thought about it and decided to just drop the issue. The man continued, "So how come you didn't walk beside me, invisibly, but still making footprints, during those difficult times? Not that I noticed you at the other times, and my life was pretty crappy and I once ate some tainted roast beef at an Arbys, but what is up with the one set of footprints?"
And Jesus said unto him, "Can you read the tshirt I have on over my robe?"
"Life's a beach?" the man read.
"Right???" said Jesus, "Do you get it? Beach? Right? Haha!"
The man looked sad, so Jesus told him, "Actually, my son, though I walked beside you all your life, during those most difficult times, at the times when you could barely go on..."
"Yes?" the man asked hopefully.
"...I just walked in your footprints because that's kind of fun and I wanted to throw off anyone following us."
"What?" asked the man.
"And I also made some dinosaur tracks."
And the man was confused.
"I don't think you get my tshirt. It's a pun..." said Jesus.
I hope that story helps. It's from the bible. Or a greeting card. But someone definitely printed it on paper.
