Alright, what bothers me, and why you and I have had a rough go of it in this thread, is when a poster has a teaching they are trying to communicate without coming out and telling the truth of what they are saying. Then they are rude and dismissive of posters who don't "get" their mystery belief. You believe there are two Gospels. Why didn't you open with that so everyone knew that is your POV? The Bible doesn't indicate that. But still instead of being rude you should have come clean on your views. There was nothing wrong with my reading comprehension. Now that I have done some research I see what you're saying in your posts, still wrong doctrine.
The Gospel of the Kingdom
In short, Christ came preaching the Gospel of the Kingdom to the lost sheep of Israel, as was promised in the Tanakh (Old Testament). We can find this promise of a future Kingdom to come in which the King Messiah shall reign in many passages including Isaiah 2:2-4, Isaiah 9:6-7, Isaiah 11:1-9, Amos 9:11-15, et al. Jesus Christ, just as John the Baptist, preached, "Repent, for the kingdom of heaven is at hand" (Matthew 4:17). Israel was called to repentance in recognition of the fulfillment of both the promised Messiah and the kingdom to come. Jesus even taught these lost sheep of Israel to pray, "Thy kingdom come. . ." (Matthew 6:10).
Believing Israel looked to the coming Messiah ben David (Anointed-One, Son of David) as the promised King of Israel who would execute divine justice (Jeremiah 23:5), establish God's kingdom on Earth (Daniel2:44), restore worship in Israel (Jeremiah 23:5-8, Jeremiah 33:6-18, Micah 4:1-2) and make peace in the world (Isaiah 2:2-4, Isaiah 11:1-10, Micah 4:3) among other things. They were very much aware of the coming kingdom (Mark 11:10, Mark 15:43, Acts 1:6, et al). Jesus commanded His disciples to preach the Gospel of the Kingdom throughout Israel (Matthew 10:7, Luke 9:2, Luke 9:60). Indeed the disciples continued preaching this gospel after His resurrection as they were commanded (Acts 3:19-21, Acts 8:12, et al). All this time God is continuing to deal with Israel according to the dispensation of the Torah, or Law. The Torah was in effect during Christ's earthly ministry and even after His death (Matthew 5:18-19, Acts 2:1, Acts 3:1, Acts 5:42, Acts 10:28, et al). This shows us that, though Christ died on the cross to be the testator of a new covenant, the Gospel of Grace was unknown to the saints at this point.
The Gospel of Grace
While Israel was commanded to repent and be baptized for the remission of sins, a justification by works, today we are commanded to believe on the Lord Jesus Christ and His finished work (Acts 2:38, Romans 4:23-25). In the dispensation of the Law, God accepted those who worked righteousness, as we see the Apostle Peter attesting to after his vision of the unclean animals (Psalm 15:1-2, Acts 10:35). Notice the stark contrast given in Paul's message of grace, ". . .to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness" (Romans 4:5).
The concept of works is key in understanding the difference between Law and Grace. Ultimately we know that we have all fallen short of God's glory and righteousness, but for those living in the dispensation of the Law, works were a necessary requirement to enter God's kingdom (Matthew 7:21). The amazing Gospel of Grace given to the Apostle Paul by the Lord Jesus Christ Himself was that Jesus died and shed His blood for our sins, and if we put our faith in the vicarious death of Christ and the atoning power of His shed blood to pay for our sins, we shall be justified in the sight of God, receive the imputation of His righteousness to our account, and thus be accounted worthy to enter God's heavenly kingdom (Romans 3-5, Galatians 1:11-12, Ephesians 1-3).
This unique, new revelation given first to Paul was unknown to the apostles before him and indeed was kept hidden from the beginning of creation (Romans 16:25, Ephesians 3:1-10, Colossians 1:25-27). The gospel given to Paul was that Christ died for our sins according to the scriptures (this truth, for example, shed illuminating light on such passages as Isaiah 53); Jesus lived a holy, sinless life so that He could provide Himself as the Lamb to atone for the sins of all who will believe upon Him (1 Corinthians 15:3)!
Conclusion
The defining factors in the differentiation of these two gospel are the method and object of salvation. While Israel looked for an earthly kingdom inherited only by those who worked righteousness according to the Law, the Church, the body of Christ looks for a heavenly kingdom inherited by all those who put their faith in Him apart from any works.
The above is what you believe and are saying in this post is it not?? To save anymore confusion and rude comments, this is what the poster is talking about. NOW people can read it and answer with full knowledge of what they are talking about. Are there two Gospels?! That is what the OP is positing, now we can all discuss on a level playing field. My answer is no, there is only ONE Gospel, ONE way to be saved.
