Not once in 45 minutes of speaking did he actually identify the gospel in the bible or what it is. This guy wouldn't know the gospel if Paul pointed it out to him. There is even an epistle where Paul was clubbing a church over the head explaining what the gospel is and what it is founded on (see Galatians) and this guy didn't even come close to identifying it.
Paul spent much time writing why the gospel doesn't rest on works of law, and he does actually tell us what the gospel is and what it rests on. It rests on God's promises and faith in his ability to perform them. And not once did this guy identify the promises or show where to look, much less mention the name Abraham or even bother with the first 80% of the bible.
It is all right there in Galatians 3:
Galatians 3:7 Know then that it is those of faith who are the sons of Abraham. 8 And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, “In you shall all the nations be blessed.” 9 So then, those who are of faith are blessed along with Abraham, the man of faith.
The gospel that Paul is quoting is recorded in Genesis and is there for all to see. It is the promise to Abraham and his offspring of an eternal inheritance (Genesis 12:1-3, 13:14-18, 15:1-6, 15:17-21, 17:1-8, 17:15-21, 22:15-19). Abraham never got the land he was promised forever, the only land Abraham owned in the promised land is his tomb. God hasn't fulfilled this promise yet (Heb 11:13).
And Paul goes on in Galatians 3 showing who that offspring is, that is Jesus the Christ.
Galatians 3:15 To give a human example, brothers: even with a man-made covenant, no one annuls it or adds to it once it has been ratified. 16 Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ. 17 This is what I mean: the law, which came 430 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void. 18 For if the inheritance comes by the law, it no longer comes by promise; but God gave it to Abraham by a promise.
And Paul goes on, and explains how the Gospel isn't just for those two, but includes those in Christ.
Galatians 3:23 Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. 24 So then, the law was our guardian until Christ came, in order that we might be justified by faith. 25 But now that faith has come, we are no longer under a guardian, 26 for in Christ Jesus you are all sons of God, through faith. 27 For as many of you as were baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. 29 And if you are Christ's, then you are Abraham's offspring, heirs according to promise.
Hebrews also explains that the gospel is based on these promises (Heb 6:13-20), firstly the sworn oath to Abraham and his offspring (Genesis 22:16) of an eternal inheritance, and second God's sworn oath to Christ in Psalm 110 that he would be the king and priest forever. It is this gospel of promises made to the fathers that Paul and Barnabas preached at Antioch (Acts 13:13-33). It was this gospel that Paul defended himself with before Agrippa (Acts 26:1-11).
And for us, just like Abraham, these promises are received by faith. As we read in Romans 4:
Romans 4:16 That is why it depends on faith, in order that the promise may rest on grace and be guaranteed to all his offspring—not only to the adherent of the law but also to the one who shares the faith of Abraham, who is the father of us all, 17 as it is written, “I have made you the father of many nations”—in the presence of the God in whom he believed, who gives life to the dead and calls into existence the things that do not exist. 18 In hope he believed against hope, that he should become the father of many nations, as he had been told, “So shall your offspring be.” 19 He did not weaken in faith when he considered his own body, which was as good as dead (since he was about a hundred years old), or when he considered the barrenness of Sarah's womb. 20 No unbelief made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God, 21 fully convinced that God was able to do what he had promised. 22 That is why his faith was “counted to him as righteousness.” 23 But the words “it was counted to him” were not written for his sake alone, 24 but for ours also. It will be counted to us who believe in him who raised from the dead Jesus our Lord, 25 who was delivered up for our trespasses and raised for our justification.
Reading the passage, note that God HAS MADE (past tense even in Genesis) Abraham a father of many nations. Paul contends that Abraham did not waver in his belief in this promise. He knew immediately that Ishmael was cut out of the inheritance (see Gen 17). And when Abraham raised the knife over his son Isaac fully intent on killing the promised son (Gen 22), Abraham knew that Isaac was going to walk out of there (Heb 11:17-19).
This is the faith we should have, that God is able to do what he has promised, that is provide a kingdom (the land), provide a king (the seed), and raise up his people (those also in the seed) to inherit the land forever....
....and not one of those promises say anything about going to heaven.
