Trusting A God We Cannot See

This I declare about the LORD: He alone is my refuge, my place of safety; he is my God, and I trust him. Psalm 91:2 
Sometimes we get criticized for expressing faith in a God we have never seen.  As I was thinking on this, there are a lot of things I believe that I do not understand.  How does electricity, which I cannot see unless it arcs and sparks, run through wire. I see the results, I am typing on a computer that uses electricity, and behind me is a light burning. I really don't understand how it works. Pictures, I love to take pictures but how do I get that view I see on paper? then how do I get thousands of those same pictures on a thumb drive? If I see a red Cardinal it come out on my picture as red, if I view it on my thumb drive it is red. I don't understand how something as small as my thumb drive can hold all the pictures. I really do not understand. Flying on an airplane, how does it stay in the air? People that know more than me tell me it is the air going over the top of the wing that gives it lift. I do not understand. I watch the humming birds flutter around and do battle over territories. They are amazing creatures, I do not understand how they fly like they do.  I plant flowers and vegetables and I get different colors of flowers from the same red or brown or black colored soil.  I get yellow corn and green okra and red tomatoes from the same garden soil. I don't understand how it happens. I drive my car every day and it starts, I have some understanding as I have taken an engine and a starter and a transmission apart and put them back together again. But once again the starter uses something called electricity and it comes from a Battery with acid inside. I don't understand how it works. I installed batteries and they do all sorts of amazing things. They tell me electricity comes out of those batteries.  Cell phones: I can call across country some 2600 or more miles away and talk to family and recognize their voice. There is no line from my cell phone to their phone and yet I can hear their voice and know it is them. I don't understand. They tell me the earth rotates on an axis, I can't see it. I see the sun and the moon move across the sky, but they tell me the sun is stationary and the moon rotates around the earth as the earth rotates around the sun. I don't know how it all happens and it stays in orbit over the centuries. I don't understand how it all happens. It seems I can go on and on about so many things I take for granted that I cannot explain fully yet I believe they exist because I can see them. I can't see electricity, or the cell phone signal, but I believe they exist.  Most of the time I cannot see the oxygen I breathe, but on a cold day I can see the moisture in the air I exhale. How come water freezes at 32 degrees? I don't know, it just does. Yes I believe in a God I have not seen. I believe he created this earth, the universe and the life that dwells upon this earth. I have never seen him but I believe in him. I pray and believe he answers those prayers. I never saw Jesus when he walked on this earth.  I never saw him crucified but I believe he was crucified for my sins.  I never saw Abraham Lincoln, or George Washington, or Benjamin Franklin but I believed they lived before me. So many things I believe that I never saw with my own eyes. Still I believe. If God is fake and a made up thing, perhaps George Washington and Abraham Lincoln and Benjamin Franklin are fake also.  I have never see them. I have seen pictures of them but perhaps someone just made up those images someway. I trust God whom I have never seen.  God bless, LVZ.
