Dispensationalism usually consists of people who see a distinction between Israel and the church. Some feel this distinction happened at Acts 2, others at mid Acts, and some at Acts 28. What is called "right division" usually takes a mid Acts position and can see an overlap between the gospel of the kingdom offered to Israel and a revelation of the mystery of the age of grace offered to gentiles. The idea that there can be two gospels seems to be supported in Galatians.
Gal 2:7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
That the gospel of grace was called a "mystery" may be because if the nation of Israel had received the kingdom, the church would not be needed.
This perspective can aid in bible study in that many have had difficulty trying to apply some of what is written to Israel to Christians today. A book like Romans can be seen as written to mostly Jews trying to understand the gospel of grace. The first letter to the Corinthians can be understood as written to mostly former pagans who were still attempting to use their practices in a Christian context.
