Who said this? I said he SUMMARIZED the Gospel. But he also went into great detail about the Gospel in other epistles.
Here's another error:
Sez who? The COMPLETE Gospel includes the fact that Christ is King of kings and Lord of lords. Therefore all those who believe on Him must receive him as both Lord and Savior.
Your basic premises are false, and but I will leave you to your own ideas.
Conversationally speaking:
The reason I stated what I did is because to say that Paul only "summarized" the Gospel, that implies that there are details left out. That's the nature of a summary. If you have a different definition for that term and its natural outflow, then I'm sure I speak for others here in that we would all like to hear it. This is interesting.
If Paul left other elements out that pertain to what is necessary for salvation, then that is indeed the sin of omission, which would be a grievous sin on his part. If you're saying that the full extent of items and actions necessary for salvation are spread across different epistles rather than for Paul to have spoken the totality of what is required for salvation, and the nature of salvation, then, again, you stand as his accuser.
So, let me ask you this: When speaking to the Corinthians, why would Paul not reiterate the fullness of the Gospel of Grace if it also included the necessity for water baptism and repentance, and/or any other "work" to seal in one's salvation? If he was only summarizing, then why did he not indicate that to them? That they were being theologically assaulted by Judaizers from Jerusalem and paganism from the culture, Paul would absolutely have spoken the entirety of what is required if there had been other elements, taking up only a few more words, or a couple of sentences in all that epistle, but he didn't.
As to your question about the Kingdom Gospel no longer being active under the Gospel of Grace, how can anything of personal effort be added to "unmerited favor?" How can anything be added to a gift? How does one earn what is imputed freely and without merit? I mean, there are many, many ways to phrase the question in showing the problem with anyone trying add to what can never be merited nor earned.
We EARN our paychecks on the basis of merit on our own part for doing the work negotiated for that check, usually by job description.
If someone hands a check to you as a gift, how would you ever be able to say that you
earned it by way of anything on your part. If it's a gift, then it's unmerited. Anything you may do on your part to earn that gift would change the very nature of that gift into something else OTHER than a gift.
So, if you can do ANYTHING to earn your salvation, then why did Christ die on the cross, and then teach Paul that it is NOW a matter of grace through faith, with nothing else in the mix by way of your works, such as baptism, repentance and endurance to the end?
Are you not sealed right now by Holy Spirit into salvation? Are you now not born again? How could anyone ever earn what is given freely?
In other words, what part of "unmerited favor" do you not understand? I mean, we can discuss that further if you like, but I would like to understand your thought processes so that I'm at least not guessing.
What do you think you did on your own part to earn salvation under grace?
