I think one of our biggest problems is that we want to keep everything under control, we do not want to think that something that is out of our control or cannot be explained... is real.
If we could see the extension of the universe, and the size of our planet compared with the universe, I think we would start to think about a superior being. something that we can't see, but is evident that is true.
You know how many asteroids could break our planet into pieces... asteroids bigger than the earth itself... is not about our atmosphere... is about something bigger than us that takes care of our safety, the food in our tables, etc, etc.
And I know many people may think, well there's million of people out there starving, why you say that God takes care of us... and the answer is simple...
In first place we are a very fragile specie, if anything in our habitat changes, it also affect us, our skin is so sensitive that we can die very easily... we have to live under specific climates in order to not die of cold or heat. and you think that the earth itself takes care of every detail? you think that the exact amount of chemicals in the air are there just cuz? you know.. if the athmosphere were like it was before... you would die in your first breath, and so many other things...
Humans didn't fix the air, humans didn't make the fruit came out of the earth with some experiments, we didn't make our own shield against everything that is in space... we didn't move the earth away from the sun or put it closer so we can have heat and at the same time don't get burn.
You know, things in our world are a work of engineering that exceeds everything known. everything is perfect.
And maybe you can say: I work to bring food to my table, but... who provide you that work? you know that theres countries were you try to find a job and you can't not because you are not prepare, but because there is no such thing as a job.
And why those people are poor.. you may say... well in first place, they are there to make us appreciate what He gave us. and to prove our hearts and our misericory to others, as God had mercy of us.
And if you study where are the poorest people in the globe, you will notice that the story of those countries have something in common: witchcraft, a inmense number of differents gods, each one with different power.
God conmdemed politeism and praise to anything that is in earth, or below earth.
Second reason... men destroy men... men are the ones who contaminated the natural sources of water in many countries, polluted the air, make wars and kill each other, waste what the earth produces, and then using it to move our cars and contaminate our air, men create weapons and use them to kill other man.
And about the Noah thing... If someone has some knowledge of the bible... the fundamental thing to know is that God has put laws. Laws that you believe it or not, they apply to us, and even if you don't believe, the laws that are written in the bible, they are actually true, and you can see it when you do something bad, and if you believe it or not, one day you will pay for it.
But even though we had tough laws, God in His great mercy decided to give his own son, Jesus to destroy our relation to the laws that he putted before. and now the law has changed.
Now if you confess with your mouth that Jesus is real and he reaised from death, you can be saved, before you couldn't.
now we have to give the other cheek, before it was teeth for teeth.
But I think our biggest problem is to believe in things more complex that our comprenhention. Like the guy who said that he is medium... I believe it, in my family... we have mediums, even witches... but everyone decides what to do with the things that God has given you.
Maybe is easy for me to belive because I've seen things that cannot be explained by any means, but I know they are true, but when you realize that this world is just a replique of part of the sobrenatural world (that is not my mind, it says that in the bible) you can understand that theres things that may seem like they're not real, but they are more real than the things that we can see and touch.
