Does God require us to have faith because Adam and Eve sinned? I remember when I first sought God, I felt like I was going out into the dark. I simply followed people at the church without really believing, but willing myself to believe. In other words, I didn't have faith, but I was obedient. Now I can see God a little more clearly than before, and I have more faith.

I was wondering if anybody has tried to connect God's demands of faith from Abraham (and us)  to the fall. Given that faith requires an obedient, seeking heart, it almost seems like this is a way to remedy the fall of humankind, and to restore our obedience to God.
Original sin began with Lucifer, the “I will” sin. Isaiah 14:13,14 “For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High.”

Eve was deceived and placed her faith in the words of the serpent rather than in the Word of God (transgressed faith ).  Mary, in contrast, placed her faith in the Word of God and said: “Let it be as you say”.  

Adam sided with Eve, “her will” rather than God’s will.  In contrast, the second Adam, Jesus Christ said “thy will be done” and bore the sins of mankind, resulting in grace being eternally extended to mankind, grace which is apprehended by faith. 

The original sin is born from a “self-sovereign" perspective, "My will be done. Do not impose your will upon my life."  Contrast: “Thy will be done on Earth as it is in Heaven."

God’s grace is tangible evidence that we should want God’s will to be done in our life.  So where does “me-centeredness" come from?  Originally, Lucifer transmitted to Eve by deception, who then transmitted to Adam by fear, or faithlessness.

Transgressed faith was the window in which man fell out of a relationship with God.  It stands to reason that man must enter into a relationship through that same window of faith.  After all, we are saved by God’s grace through faith.
