Why is there suffering?

This question is asked by many people, but maybe there isn't a certain answer. Suffering happens all around the world, to everyone, whether they deserve it or not, and no matter what we can't no anything about it. Suffering was introduced into this world with free will, when Adam and Eve disobeyed God in the Garden of Eden. People suffer because of sins that have happened in the past or present all around the world, not necessarily sins caused by the person/people that is/are suffering. Understanding why suffering happens is hard for many people, but whatever happens we know god will be there with us, and that is what we have to hold onto throughout our tough times.
In my life, i haven't really badly suffered yet, but i know i might one day and i can't do anything about that and god will be with me through it. One of the things that make me hate and really disagree with suffering is when you watch someone close to you suffer, sometimes its even worse than suffering yourself. When you are suffering or someone else is, you think, why is this happening? we don't deserve this, but really there is no easy answer. For example, my cousin past away in a car crash, and was only 20, he deserved to live for so much longer, this made my family suffer terribly. When your upset about these types of things, you get angry at god and at the concept of suffering, why should it happen to innocent people? but although suffering is horrible and makes you think it ruins everything, sometimes it makes you stronger, and even if it feels like its the worse thing that could ever happen, you get over it eventually, and in the end you have a different perspective on suffering and you realize that god is with you always.
Suffering exists because of previous sins cause by the world, it exists because of our free will, without free will we wouldn't have suffering, and without suffering we wouldn't have free will. Free will allows us to do what we want, and if we want to sin we can, but there are consequences, and suffering is a main example. In my opinion i would rather this world with no suffering, it would be a happy place, or maybe it would be better if the person who did the sin got the consequence, because that seems fair.
When i think of God i think of someone who is powerful, invisible, even magical, its hard to understand why he would allow us to suffer like this. I thought he could change anything and make good things happen, and even if God had the choice to take away suffering from this world, he would take free will away with it.
There is this poem called footprints, it really makes me think about how much god really is there for us, he will always be there, and that makes me happy.

Footprints in the Sand

One night I dreamed I was walking along the beach with the Lord.

Many scenes from my life flashed across the sky.

In each scene I noticed footprints in the sand.

Sometimes there were two sets of footprints,

other times there were one set of footprints.

This bothered me because I noticed

that during the low periods of my life,

when I was suffering from

anguish, sorrow or defeat,

I could see only one set of footprints.

So I said to the Lord,

"You promised me Lord,

that if I followed you,

you would walk with me always.

But I have noticed that during

the most trying periods of my life

there have only been one

set of footprints in the sand.

Why, when I needed you most,

you have not been there for me?"

The Lord replied,

"The times when you have

seen only one set of footprints,

is when I carried you."

There is some suffering in the world that no matter what we can't do anything about it, but there is some that we can help, and helping people can help your understanding, maybe it could be in this world to make the world come together and help each other, for example, in Africa, there are places where the people living there are so poor that they die of starvation. But we can help them, because we wouldn't like to be in there position, there are many ways to help people from suffering. I know that God would want me to help the unfortunate people that suffer, and i would stand up and fight with them. One of the strongest people would have to be the people that suffer from cancer and fight it. Cancer is one of the worse things ever, there is no cure and it happens to little kids and adults, they suffer for no reason, but we can help them. To help cancer you can do many things, you can donate money, spend time with them and make them feel happy, start a fundraiser and more. I would go out of my way to help these kids and give them the life they deserve, i would start a fundraiser and raise money for the kids. I would also be a "make a wish" granter, and go around to all the kids and help them get the one wish they have always wanted. Helping the kids in Africa is sometimes hard, you would have to have a lot of free time and money, but i would do whatever it takes to make them feel like they deserve a good life. I would set up a fundraiser to provide food, water, education, child care and so much more for the children suffering in Africa.
There are many other ways to help suffering kids and adults, there are people suffering all around the world! so please, take your time to help.
