1. The gospel of the kingdom takes us back to David, with whom the covenant of the kingdom was made.
2. The gospel of the circumcision takes us back BEFORE David to Abraham, with whom the covenant of circumcision was made.
3. The gospel of the uncircumcision takes us back before David and Abraham to Abram who, as an UNcircumcised heathen, was justified by faith.
4. The message of reconciliation (the gospel of the grace of God) takes us back before David, Abraham and Abram to ADAM, the "one man" by whom the world was alienated from God.
5. The mystery (The gospel of God) takes us back before David, before Abraham, before Abram, before Adam to GOD HIMSELF and "the good pleasure of His will."
There is also "my gospel" that Paul writes of through the Holy Spirit. Whereby we will ALL be judged one day. The ONE GOSPEL of today.
All of the are dispensational, BTW.
The problem is that you have to begin by removing Galatians 3 among other things, from the Bible before considering Dispensationalism. I am not willing, whether by the reformation or their offshoots in the last 150 years, to see the Canon of Scripture established by the Holy Spirit acting through the Catholic Church altered to fit a particular theology or doctrine.
Peace be with you.
With the Catholic Churches belief that the church replaced Israel its no wonder they cant rectify what scripture is really saying. Trying to apply all of scripture to all peoples from all times is bound to cause confusion.
