As I understand it, God put us here to worship him. Then he will grant us everlasting life in the Kingdom of Heaven. So I guess, this is a test. Kind of weeding out all the nonbelievers, evil doers, and etc... When Adam and Eve was created, they lived in the Garden of Eden, which was like Heaven. They didn't have to worry about anything, but Eve ate or did whatever she wasn't suppose to do, and they got kicked out, which made us all punished. Made women have to give painful child birth, and etc... Maybe that is why men have it easier than women. Then God sent Jesus down to take our sins, so we could join him in Heaven.
I do know where you are coming from. It seems like all I do is get up, go to work, come home, take a shower, go to bed and then back to work again. What kind of life is that? My job barely pays the bills. No time or money to do things fun. I know that when people have kids, they live for them.
I am white, I do not have it easy. My mom (white) worked in the cotton fields like everyone else. My family was very poor. I even had to work in a pepper field with prisoners when I was a child. You think picking cotton is bad, try picking peppers and then forget and stick your finger in your eye or mouth. Your fingers eventually started burning.
My life was horrible growing up. But I found a great man to spend the rest of my life with. He makes me very happy and I guess I live for him and God. I guess you just have to find simple things in your life that makes you happy. If not, you want have the will to live.
