I think you asked a relly good question. I would like to give you something to think about. It was never GOD'S purpose that we live a while on earth, struggling and in pain. God provided everything in the garden of Eden for us to live in complete peace and happiness. He provided a delightful and delicious abundance of food for us to enjoy. He provided fulfilling work in a beautiful environmrnt for us to enjoy.
It was Adam and Eve through the treachery of the devil, that caused us to loose all of this.
Because GOD loved us so much, he allowed his son, Jesus Christ to sacrifice his life so that we would be able to have a renewed relationship with GOD, so that we could have the hope of living once again for eternity on earth.
Both God and Jesus gave up so much for us to be able to have these things and more. They did this because they truely care. It is very hard to see the struggling that people face in their lives everyday. But it was not GOD who caused it, and he made it possible to have a wonderful hope for our future.
I hope this helps.
