The Edge,
In a nutshell, Acts 9 Dispensationalism is the recognition that God shifted from working with Israel to working with the Body of Christ beginning with the Apostle Paul's conversion in Acts chapter 9, and that the "house rules" for the two groups are not the same. For example, Israel was to express their faith through works (James 2:17), but grace is imparted to members of the Body who believe apart from works (Romans 4:5).
