So what??!!
It's not as if Paul's Gospel is completely different from what came before in every respect. It is still based on the work done on Calvary. The difference primarily centers around works of the flesh.
The Kingdom Gospel says: “I know your works, that you are neither cold nor hot. I could wish you were cold or hot. So then, because you are lukewarm, and neither cold nor hot,I will vomit you out of My mouth."
Grace said that!!
The Gospel of Grace says: "To him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness, just as David also describes the blessedness of the man to whom God imputes righteousness apart from works"
Grace is NOT refering to salvation in the above. Grace is saying that because of the cross God is now able to impute HIS righteousness to the one who is righteous. The one who had been waiting in the abode of the dead, paradise, Abraham's bosom, for Jesus Christ [imputed righteousness] to descend there to free him.,
It's not the same and Paul is the line of demarcation. If what Paul preached was the same then there would have been no reason to make Paul an Apostle in the first place because God already had twelve apostles. If it had been the same there would have been no need for the Jerusalem council where Paul had to go explain his gospel to the Twelve and after which the Twelve agreed with Paul that he should go to the Uncircumcision (i.e. to the people without the Law) and that they would minister to the Circumizion (i.e. to the people of the Law) (Gal. 2).
Paul explained grace and how it can only be received. Being a heart issue makes it a "no brainer".
This is the reason why all your proof texts are in passages written by Jesus, Peter, James and John, while all your problem texts are written by Paul. And this particular doctrinal debate isn't the only one that has Paul as the line of demarcation either. There's a whole list of seemingly unrelated issues that have the exact same characteristic.
Uh, I have no problem.
As in "forfeited"? Yes.
Are works necessary for salvation?
No.
Will the rapture occur before the Tribulation?
Halfway through it. See Rev. 11:5;12:6;13:5.
Should Christians eat "unclean" foods?
There is nothing unclean that God has made clean, which covers everything.
Should Christian observe the Sabbaths?
All days are sabbaths for the Christian. Define Christian.
Is water baptism required?
Nope.
Should Christians expect physical miracles to happen?
Expect? The man of the Pentecostal gift of Faith might because he lives by the faith
of the Son of God.
Are there still Apostles today?
Yes. Missionaries in abundance are all over the world dying preaching the grace of God and making disciples to Jesus Christ..
And there are about a hundred variations of those (and others) that are either directly or indirectly responsible for nearly all of the various divisions within the Christian church. Just about every denomination you can think of has one form or another of these doctrinal debates to thank for their existence.
You have nothing to blame it on but your embraced warped doctrine of legalism, which you "rest in".
God's grace is NOT unmerited..nor is it administered by Him through some special man made precepts.
"And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God." Luke 9:62 (KJV)
Can you see how grace works in that verse?
