We know his topic he unpacked for them when he first met the non-believers in Corinth . . . 1 Cor 2:2 . . . I resolved to know nothing while I was with you except Jesus Christ and him crucified . . . but what exactly did he say to them? Jesus was Paul's topic, but what specifically did he say about Jesus that got so many to follow Jesus? Philip has the same topic with the Ethiopian Eunuch in Acts 8. Paul says in Galatians he compared what he said to non-believers with what the rest of the Apostles presented, so there must have been a loose outline of presenting Jesus everyone agreed on.
Did he give unbelievers the four spiritual laws? If so, that would be important enough would it not to be listed in the Scriptures as his outline?
Paul did not have a New Testament . . . so what did he say to them exactly? Whatever he said, it says in Rom 1:16-17, whatever he said was the ultimate power.
What was the Apostle's outline? I would really like to know.
I believe Paul's outline is that it was Jesus faithful obedient sin atoning work that paid for & conquered sin. And our faith place in it/Him whereby a believer is forgiven/saved
Rom 3:25 “Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;”
1 Jn 4:10 Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.

Gal 3:22 But the scripture hath concluded all under sin, that the promise by "faith of Jesus Christ" might be given to them that believe.

Phil 3:9 And be found in him, not having mine own righteousness, which is of the law, but "that which is through the "faith of Christ", the righteousness which is of God by faith:

Habakkuk 2:4 Behold, his soul which is lifted up is not upright in him: but "the just shall live by his faith".

Gal 2:16 Knowing that a man is not justified by the works of the law, but by the "faith of Jesus Christ", even we have believed in Jesus Christ, that we might be justified by the "faith of Christ" and not by the works of the law: for by the works of the law shall no flesh be justified.
(NOTE: It's the Faith "OF" Christ & thru the righteousness of Christ's obedient works. That when we place our faith in Him & His work. Christ becomes the Lord our righteousness (Jer 23:6 & 33:16). And God judicially justifies us ="Declares us Righteous in His sight)
