Did the Fall cause us to be conceived in a sinful condition, separated from God? My answer is yes. Had we sinned or done anything good or bad? My answer is no. Thus Adam's sin was not imputed to us. But the consequence of his sin, separation from God and corruption did result in our sinful condition at conception. Were our sins and our sinful condition washed away by Christ's one sacrifice on the Cross? No. Only those that "receive" the reconciliation provided by Christ's one sacrifice on the cross have their sins washed away. God must credit our faith as righteousness, and then place us in Christ, the sanctifying work of the Spirit, in order to receive the washing of regeneration. Bottom line, the nice sounding doctrine avoids the sequence given in scripture for salvation.
