Job 8

It is really dangerous when one being alone is very down. Luckily Job has 3 loving friends who come to keep him company even though Job's wife fretted him and complained why Job hadn't been dead..... One of Job's friend, Bildad thinking of the logics of blessings for righteous & curse for evildoer. He stopped Job from grumbling and tried to divert him to think what the wrongs done so deserving a penalty to him. He should learn the lesson. God does not reject a blameless man or strengthen the hands of evildoers. (Job 8:20)

Whether or not this will help Job or not, nevertheless, Job stopped thinking negatively and turned to focus at God and thought of God.

This is a way when one's fallen in the valley of depression. Think of God and energy will surge. Believer or not. You'd better believe.
