Paul got his gospel from the Hellenism of Greek Mythology.
Nope! Paul got it by direct revelation of Jesus Christ as the scripture saith (Galatians 1:11-12 KJV).
Yea, his gospel was after the Hellenistic doctrine of the demigod which is the son of a god with an earthly woman. (Acts 9:20)
Why do you blaspheme? Colossians 1:13-19 KJV
If Jesus revealed any thing to him, how come the Apostles of Jesus did not know it?
You don't think God can keep a secret? (Romans 16:25-27 KJV, 1 Corinthians 2:6-8 KJV)
When Paul applied to join the Apostles he was rejected under the pretext that he could not even be a disciple. (Acts 9:26) Weird, isn't
it?
Saul was a man who led the persecution against those of "this way" (Acts 9:1-2 KJV, Acts 22:4-5 KJV)/persecuted the church of God and wasted it (Galatians 1:13 KJV), consented unto the death of Stephen a man full of the Holy Ghost (Acts 8:1 KJV) disqualifying him for forgiveness under the kingdom program (Matthew 12:31-32 KJV), so yes, I would say that they were SHOCKED that he was a chosen vessel of the Lord as Paul being saved was something the Lord had never done before (1 Timothy 1:16 KJV)!
I already trust the Lord as a member of the Faith of Jesus which was Judaism.
Galatians 5:2 KJV
The only power of God that saves man is obedience to the Law.
You are dead wrong! The gospel of Christ is the power of God to save you!
Romans 1:16 For I am not ashamed of
the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
It is the righteousness of God WITHOUT THE LAW and is upon all them that believe!
Romans 3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
Romans 3:22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
Believe what? The gospel of Christ, that's what!
1 Corinthians 15:1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
1 Corinthians 15:2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
1 Corinthians 15:3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
1 Corinthians 15:4 And that he was buried, and that he rose again the third day according to the scriptures:
Jesus himself implied with his parable of the Richman and Lazarus that the only way to be saved from hell-fire is by listening to "Moses" aka the Law. (Luke 16:29-31)
That's not our good news! The good news is that even though the wages of sin is death, Christ took the payoff! He paid the debt in full (Romans 6:23 KJV)!
2 Corinthians 5:19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
2 Corinthians 5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
Trust the Lord believing the gospel of Christ (1 Corinthians 15:1-4 KJV)! It's your only hope!
