The gospel messages documented throughout the book of Acts and the Epistles are not identical. Most Christians fail to discern the differences in the New Testament gospel messages preached by the Apostle Peter and by the Apostle Paul.
“[T]here are two Gospels, each dependent upon the Blood of the Cross. The one Gospel is earthly (Kingdom), the other is heavenly (Grace). Both Gospels are “according to Jesus, ” and present only one way: by faith.
One Gospel was ministered by Christ on earth, during His pre-Cross humiliation, and was exclusively addressed to Israel regarding her Millennial Kingdom. The other–altogether “new creation” other–was ministered to Paul by the glorified Lord Jesus Christ; after Calvary, from heaven, exclusively to and for His Chosen heavenly Body.
John the Baptist’s, Jesus’, and the Apostles’ Gospel concerned the Messiah and His Kingdom–specifically and repeatedly referred to as “the Gospel of the Kingdom” (Matt. 4:23; 9:35; 24:14; Mark 1:14; Lu. 9:2,6). The other, “the Gospel of Grace of God,” was neither preached nor mentioned until Paul went forth to declare it (Acts 20:24; Rom. 3:21; Eph. 3:1-3).” Miles J. Stanford, Pauline Dispensationalism, pg 5.
