Book of Psalms

I feel as though in the Book of Psalms, I get this impression that if you don't follow God's righteous path you are doomed.  For example, chapter 2, verse 5 "Then will He speak to them in His wrath, in His burning anger dismay them."  This chapter speaks of the consequences of misjudging the worship of God.  

However, by worshiping God faithfully one should have nothing to fear.  Chapter 30, verses 3-4, "Lord, my God, I cried to You and You healed me."  By turning to God he will help you.  Also in chapter 30, verse 8 "Lord, in your pleasure You made me stand mountain-strong.  When You hid Your face, I was stricken."  In this passage God has given great security to those in need and those without him are most definitely lost.  The Psalms use of capitalizing "You' and "Your" really emphasizes God's majesty.

Ethically speaking, by following God according to the Book of Psalms, he has all the answers to live by.  Typically, God demands will save you.  From the beginning of mankind up to the Book of Psalms, every person has committed an act of wrong doing.  In human nature it has been impossible.  In today's standards, living by the rules of God I believe is especially harder.  This ethic sums up the ethics of Christianity or Judaism.  The question is whether if they are rules to live by and to follow them with the best of one's ability or will the people of mankind find out that they are condemned?  I think that if the latter were the case no one would be saved.  In short, by worshiping God faithfully, one might make mistakes but by gaining God's forgiveness nobody will have anything to fear.  By avoiding those who will lead you down the wrong path, you can pull through.  Chapter 35, verse 8, "Take my part, Lord, against my contesters, fight those who fight against me."
