Two years:
Act 19:9,10 But some of them were stubborn and would not believe, and before the whole group they said evil things about the Way of the Lord. So Paul left them and took the believers with him, and every day he held discussions in the lecture hall of Tyrannus.
This went on for two years, so that all the people who lived in the province of Asia, both Jews and Gentiles, heard the word of the Lord.
Paul visited Corinth during his second missionary journey, where he stayed for over a year and a half. He visited Athens during his second missionary journey as well, after leaving Berea and before arriving in Corinth.
1 and 2 Thessalonians were written during Paul's Second Missionary Journey.
On Barnabas's second missionary journey, he took John Mark and sailed to Cyprus, which was Barnabas's home island. They aimed to revisit the churches they had established during their previous missionary work. However, their journey later diverged as Paul chose Silas for his own missionary efforts, leading to separate paths for Barnabas and Paul.
Paul visited several key destinations during his missionary trips, including cities such as Antioch, Ephesus, Corinth, and Rome. These cities were important centers of trade, culture, and religion in the ancient world, and Paul's visits helped spread the message of Christianity to a wider audience.
During Paul's missionary journey, significant events included his conversion on the road to Damascus, his preaching in various cities such as Antioch and Corinth, his conflicts with local authorities and religious leaders, and the establishment of new Christian communities. He also wrote several letters to these communities, which later became part of the New Testament.
The culture in Ephesus consisted of the same culture found in Turkey today since Ephesus is found in modern day Turkey.
During Paul's second missionary journey he spent 1 year and 6 months at Corinth.
I believe the scripture says they were in Philippi, the chief city in Macedonia . Acts 16:12
AnswerRaymond E. Brown (An Introduction to the New Testament) says that the three journeys are only a convenient classification developed by students of Acts. He finds difficulty in reconciling the itinerary identified in the Book of Acts with Paul's own description of his itinerary. When talking of Paul's epistles it is safer to relate them to his own account of his mission and therefore not to the three missionary journeys described in Acts, written more than half a century later.
Paul founded several churches during his missionary journeys, including the churches in Corinth, Thessalonica, Philippi, and Ephesus. These churches were located in various regions of the ancient Roman Empire.
There is no current population data available for Ephesus, as it is an ancient city located in present-day Turkey. However, during its peak in the Roman period, Ephesus was estimated to have a population of around 200,000 people.
John Mark left Paul during the middle of Paul's first missionary journey as recorded in Acts 15: 37-40
