I am a Christian and everything that is happening is recorded in the Bible. . I hate seeing people get killed and hurt, makes me really sad. But I know God is in control.
If its bothering you (and it bothers me as well) watch a 1/2 of the local news and the 1/2 of world news a night. That way you can keep up in the going ons and not stress out so much. Then turn on something else.
