In an old and problematic scheme of things, it does not matter whether the gospel is presented accurately or not, no human being is able to respond to it appropriately anyway, because everyone in their natural fallen state suffers from total spiritual inability.
Then, again according to the outdated view, those individuals that were pre-selected before creation to be saved, are altered supernaturally by irresistible grace, such that they come to Christ. In such a scheme, the message does not matter, only whether or not God choose the foreseen individual for salvation.
Paul drives an alternate view home in Philippians 1:15-18. Paul says it does not matter if you hear Christ proclaimed from a person motivated by compassion and good will or from a wolf in sheep's clothing, because the message is everything.
In Matthew 23:13 we read where folks have responded to the message and are actually in the process of entering heaven when they are blocked by false teachers. So either the folks had some spiritual ability or they had received "irresistible grace" but then the grace could not have irresistible for they were blocked.
Bottom line, the gospel of Christ is the power of God unto salvation.
Beware of False Teachers
Matthew 7:15,16 Beware of false prophets, who come to you in sheep's clothing, but inwardly they are ravenous wolves. You will know them by their fruits....
2 Timothy 4:3,4 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; and they will turn their ears away from the truth , and be turned aside to fables.
Acts 20:29-31 For I know this, that after my departure savage wolves will come in among you, not sparing the flock. Also from among yourselves men will rise up, speaking perverse things, to draw away the disciples after themselves . Therefore watch, and remember that for three years I did not cease to warn everyone night and day with tears.
Matthew 15:9 And in vain they worship Me, Teaching as doctrines the commandments of men.
2 Peter 2:1 But there were also false prophets among the people, even as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Lord who bought them, and bring upon themselves swift destruction. Consider who denies Jesus bought those heading for swift destruction with the false doctrine of limited atonement.
2 Peter 3:16,17 as also in all his epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures. You therefore, beloved, since you know this beforehand, beware lest you also fall from your own steadfastness, being led away with the error of the wicked;
Colossians 2:8 Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ.
Hebrews 13:9 Do not be carried about with various and strange doctrines. For it is good that the heart be established by grace, not with foods which have not profited those who have been occupied with them.
Clearly then, the gospel of Christ can be corrupted by the traditions of men, and the results can prevent folks from entering heaven. So we should stick with what the Bible says, and not add stuff never mentioned in the Bible, such as the folks of Matthew 23:13 entered heaven later. We are to believe what it says, not believe in things not said. Extrapolations based on logical necessity are fine, but saying one of a number of possible extrapolations is doctrine is unsound.
