Acts describes Paul’s three missionary journeys along the northeastern shores of the Mediterranean Sea. Here, the Romans ruled, and it was a time of Pax Romans, or Roman peace, where Paul could travel in relative safety. As a Roman citizen, Paul could go anywhere, and everyone spoke Greek. Romans built hundreds of miles or roads, many of which exist even today.
God had set Paul up for this job. He was a Pharisee who studied with Gamaliel, and he fully understood being Jewish and being a Roman citizen. He used his knowledge of languages to connect with people, and he performed miracles when needed (such as the guy who fell out the window). Paul established many churches and helped to raise up the next generation of Christian leaders. Not bad for a life well lived. Plus, he got to see and experience God and Jesus.
