Please watch this video teaching the Acts 28 position. I have watched it 7 times and see no problem.
Repentance is a change of mind. For the Gentiles it means to “turned to God from idols” (Thessalonians 1:9); as seen in Acts 17:16…29-31 which says:
“Now while Paul waited for them at Athens, his spirit was stirred in him, when he saw the city wholly given to idolatry. … Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device.
And the times of this ignorance God winked at; but now commandeth all men every where to repent: Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.”
And as a result of Paul’s preaching verse 34 says: “Howbeit certain men clave unto him, and believed …”
The Apostle Paul never says “repent and believe.” When a person believes, they are changing their mind from whatever they previously thought to believe in the truth of the gospel.
The first recording of Apostle Paul’s message when preaching the gospel is also the first time “justification” is preached in the Bible, is Acts 13:38,39:
“Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins: And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.”
“Believe” is always the only thing he called on sinners to do to be saved. Here is a sample list:
Act 14:1 “And it came to pass in Iconium, that they went both together into the synagogue of the Jews, and so spake, that a great multitude both of the Jews and also of the Greeks believed.”
Act 16:30,31 “And brought them out, and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.”
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.”
Romans 3:21,22 “But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; 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:”
Romans 3:28 “Therefore we conclude that a man is justified by faith without the deeds of the law.”
Romans 4:3 and jumping to the end of the chapter, Romans 4:23-25 says: “For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. … Now it was not written for his sake alone, that it was imputed to him; But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; Who was delivered for our offences, and was raised again for our justification.”
Then Romans 5:1 concludes: “Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:”
1Corinthians 1:20,21 “Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world? For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.”
The Gospel in its essence and simplicity is found in I Corinthians 15:1-4 which says:
“Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:”
To “believe in vain” according to I Corinthians 15:14 & 17 is to not believe that Jesus Christ rose from the dead – “And if Christ be not risen, then is our preaching vain, and your faith is also vain. … And if Christ be not raised, your faith is vain; ye are yet in your sins.”
But according to verse 2, if you believe verses 3&4, then “ye are saved.”
This is the “simplicity in Christ” –
II Corinthians 11:3,4 “But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.”
