Instruments in the Redeemer's Hands

This month's book is Instruments in the Redeemer's Hands.
It is a biblical counseling book that I have been encouraged to read over the past few months. There are several of us embarking on the journey of reading this book and hopefully learning from it.
Already, in chapter 3, I am being challenged to consider who influences me and how I influence others as I interact with them. Three principles are focused on in this chapter. "First, we were created with the need for truth outside ourselves to live life properly. Second, many interpretive voices compete with God's Word for our heart's attention. Third, the power of sin has been broken, but the blinding presence of sin remains."
While the first and third principles are just as true as the second, the second one really grabs my attention. What other voices compete for our heart's attention? Satan wants me to believe that I don't need God and that I am completely self-sufficient. The world around us wants us to believe that I don't need anyone but myself for true happiness. But that goes against what God tells us in the Bible. His wisdom meets our need and gives us purpose. He created us to need Him according to Genesis 1.
Why did Eve choose to believe the lie of Satan in the Garden of Eden?
What was so tempting to her about that lie?
Who are the voices that help you interpret your own life?
How can we be a part of the world around us, but still allow the wisdom of God to help us interpret life?
