The Gospel Feast

Who are those called just in Scripture? Is every chosen sinner vital to God? How is the elder son an example of pride of place? How are all by nature either like the prodigal son or the elder son or both? Does the type of sinner have any bearing on God's love and effectiveness in saving that sinner? Is there any sinner that's better than others? How does the Spirit cause us to consider our lost estate? Is there a difference between God as a Creator and God as a Father?
