Act 17:2ff, “And Paul as his manner was, went in unto them, and three sabbath days reasoned with them OUT OF THE SCRIPTURES, OPENING AND ALLEGING THAT THE CHRIST MUST NEEDS HAVE SUFFERED, AND RISEN AGAIN FROM THE DEAD, AND THIS JESUS WHOM I PREACH UNTO IS THE CHRIST.
And some of them believed, and consorted with Paul and Silas, and of the devout Greeks a great multitude, and of the chief women not a few.
But those of Yudah (the Jews) which believed not, were moved with envy…”
Paul preached the gospel, men heard and God gave grace to believe or not. For the gospel is the power of God unto salvation to everyone who believes. For we are saved by grace through faith, it is the gift of God-the faith of Jesus. For Jesus the Christ is the author and finisher of the faith.
