The Gospels of the bible
I think most would believe there is only one gospel that saves a person today. Though would disagree on what that gospel is. But the bible does have a number of different gospels in it. Which one do you believe?
The gospel given to Abraham -
Gal 3:8 KJV And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed.
The gospel of the kingdom - the gospel of the circumcision -
Mark 1:14 KJV Now after that John was put in prison, Jesus came into Galilee, preaching the gospel of the kingdom of God,
Mark 1:15 KJV And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
John 20:31 KJV But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
The gospel of the grace of God - the gospel of the uncircumcision -
1Cor 15:1 KJV Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
1Cor 15:2 KJV By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
1Cor 15:3 KJV For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
1Cor 15:4 KJV And that he was buried, and that he rose again the third day according to the scriptures:
Rom 16:25 KJV Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
Rom 2:16 KJV In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.
Eph 3:6 KJV That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:
Gal 2:7 KJV But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
The everlasting gospel -
Rev 14:6 KJV And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,
Rev 14:7 KJV Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters.
Each one of these gospels had different requirements to put their faith in. This verse alone mentions 2 of the gospels.
Gal 2:7 KJV But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
To believe there is only one gospel in the bible or that Peter and Paul preached the same gospel would be a gross error in one's bible study.
