They were apostles of Christ. Sent directly by him. They had the apostolic authority of being apostles of Christ and eyewitnesses. They had the gift of the prophetic word of the Holy Spirit (inspiration) to listen to them audibly was the same as listening to the bible (2 Peter 1) Today we can only hear authentic apostolic teaching from the New Testament. It is the New Testament that makes the church apostolic.
But, for Paul to refer to his being "set aside from birth," as an example, when defending his authority suggests that such a characteristic is unique to him and not common to all believers. So too with regard to his being individually picked and effectually drawn. To suggest these are common attributes for all believers would seem to diminish his authority in that the individual believers could rightly respond saying, "So what, Paul? We are all set aside from birth, individually selected and effectually called, what makes you think you are special? We all have similar testimonies. Who is to say what you think is any more authoritative than what we think?"
Total depravity is not utter depravity. It doesn't mean that man is as wicked as he can be all the time. There is grace given by God that restrains a man from being utterly depraved. As God's grace is removed from a man he gets closer to utter depravity. So to harden a man all God has to do is remove a level of restrainst from a man.
But in all the passages regarding the hardening of Israel (Mark 4; Matt. 13; Acts 28:21-28; John 12:39-41; Rom 9-11; etc) there is the CLEAR distinction between those who have "become hardened" as ones who cannot "see, hear, understand and repent," and even the distinction showing "otherwise they might have" done so. In fact, Paul in Acts 28:28 goes as far as to point out that the Gentiles, unlike the hardened Jews, "will listen." Total Depravity teaches these abilities aren't present from birth making such passages meaningless.
Because in God's economy of time that was the right thing to do. A plain representation of the gospel would have brought mockery and blasphemy from the lips of unregenerate man as it does today.
The problem with this answer is that it is NOT the reason given by the scripture. The reason the gospel truth is hidden in parables is "lest they see, hear and believe it so as to repent." God wants to keep them in the dark for a period of time and if born totally depraved this would be accomplished by simply not regenerating them.
Since the gospel is the "power of God unto Salvation" it had to remain hidden until the proper time. The time in which ALL MEN would be drawn to HIM. (John 12:32)
Because it is a tool which God has chosen to use to stimulate them to gospel exposure. God regenerates his elect during their exposure to the gospel.
Tools typically are used to accomplish a specific purpose. What purpose does the tool of envy serve? You say it is to "stimulate them to gospel exposure," but what does that even mean? Only the work of effectual regeneration makes men capable of receiving the gospel, so what possible work is really being accomplish by the means of envy? Isn't it a provoker of man's will, so as to persuade and change their wills?
This is the same general theme question as why didn't God just create a perfect world with no suffering?
Actually they are quite different. A Calvinist would have a reasoned and logical answer for this question, but to my question regarding why God might choose to provoke the will to envy they resort to red herrings? Or say ambiguous things like, "it is used to stimulate them to gospel exposure."
No, because the people he spoke to were given promises of God's providence and their perseverence in the faith.
I'm not sure how that negates my point???
There is also the story of Jonah to consider regarding God bringing salvation to other groups than just Jews, God's compassion for the Ninevites was common knowledge
But, to the Jews of that day certainly you know of their destain for the idea that Gentiles were being invited to enter Covenant with "THEIR" God...the God of THEIR forefathers. Even the Jewish believers were trying to force the Gentile believer to convert to Judaism in order to be Christians. Plus, do a search on "mystery" in the NT and you will clearly see that this mystery has everything to do with God's choice to bring salvation to nations other than Israel. Surely, you don't deny this, do you?
