The Bible and God's Sovereignty

If you want to further explore the topic of God's sovereignty, here's a few passages to plow through:

1. Isaiah 40
2. Ephesians 1:1-13
3. Ephesians 2:8-9
   
4. Romans 9-11

While you're at it, try to answer the following questions with as much support from these texts as you can muster:

1. What role does a human being play in salvation?
2. Where does the faith to believe come from?
3. How significant is human decision in determining the course of human history?
4. What role does human sin play in whether or not God chooses to adopt a person as His child?
5. How does a person receive salvation? To say it another way, what must I do to be saved?
