Being apart of this Picture called "LIFE"

I cant seem to understand why bad things always happen to good people...... lately i have wondered is there anything i could do to help prevent the hurt and the catastrophic events that occur throughout life;but i cant . I don't have those kind of powers.... I don't have any powers. The only thing i can do is live to fight another day through the pain. I feel as if GOD is gonna work things out for those who trust and love him and do what he has command of us , but i don't know if  I can sit back and just watch things fall in place . I feel useless. We say that a picture can speak a thousand words. Well i believe that the picture called "Life" will never stop speaking , because everyday we add a little more graphics and illustration to it everyday!
