Apparently we do diverge on the meaning and extent of the consequences of spiritual death. What makes you think I see sin entering the world and the being of man in some light way, or that I view separation from God in some light way? Maybe you don't have an idea of the extent of all that I include in man being separated from his Creator and what it has taken for God to resolve the matter and bring man back to Him.
I don't see the need for getting into the fall and the change in man and what was required to deal with sin when we're now discussing faith and whether or not man retained the ability to have faith in what God revealed to him throughout history. If you think you have some point to make from the fall, then by all means explain it.
Do you have answers to how Scripture discusses the fact that men have had Faith at minimum from Abel through the revealing of God's Son and to what
@PaulThomson has pointed out re: the object of Faith?
Maybe you've answered this. I'll move on.
