Amphipolis (Ἀμφίπολις) was a major city in Macedonia, located on the Strymon River near the Aegean coast. It was a strategic Roman provincial capital that Paul passed through on his second missionary journey.
Amphipolis represents the unstoppable advance of the gospel. Paul and Silas passed through it on their way from Philippi to Thessalonica (Acts 17:1), undeterred by their recent imprisonment and beating. The strategic placement of this Roman city — a provincial capital on the major road (Via Egnatia) — illustrates how God used the Roman road system to spread the gospel from Jerusalem to the ends of the earth (Acts 1:8). The gospel did not skip important cities; it moved through them, carried by servants who had been beaten but not silenced, imprisoned but not defeated.
