THE SIMPLE GOSPEL OF GRACE 1st Epistle of Paul Chapter 15 to the The Corinthians Greece

The gospel isn’t a matter of religious opinions, platitudes, or fairy tales; it is about real historical events.
The death of Jesus Christ, the Messiah, the Son of God, is the center of the gospel. Though the idea of glorying in the death of a Savior seems foolishness to the world, IT IS SALVATION .... to those who will believe.

Paul's Correspondence with the Corinthians

The account of Paul's first visit to Corinth is recorded in Acts
18:1-17. The Apostle Paul had found himself in Corinth after

passing through Athens (c. AD 51). When he came to the city he

found a Jewish couple, Aquila and Priscilla, who were there

because Claudius had expulsed the all Jews from Rome.

Incidentally, they too, like Paul, were tentmakers by trade and so

Paul stayed and worked with them. As it was his practice to go to

the Jew first (Rom 1:16, etc.), he visited the local synagogue every

Sabbath. Silas and Timothy met up with Paul after their extended

stay in Macedonia. They brought support from the Macedonians

so that Paul could be "occupied with the word." Paul's ministry to

the Jews ended up being unsuccessful (they opposed and reviled

him), therefore he decided to go to the Gentiles.
