We make choices every day -
Do I wear the green shirt or the blue shirt today? Should I buy a Chevy or a Ford...
In this I will grant that we have a free will. We can choose at any given circumstance whether to do one thing or another, even to the point of whether to sin or not. We do have those choices. Where we do NOT have a choice is to honor, glorify, rejoice in, or seek God. There is no choice in that. We (before regeneration) are sinners dead to God. We cannot choose to become alive in God. Not on our own action, decision, desire or in any other way. God chooses us. Then he paves the way for us to believe in him.
What then is "Original Sin" if not the knowledge of the difference of good and evil and the ability to choose our own path?
