Exeimi combines ex (out of) and eimi (to go). It appears in Acts 13:42; 17:15; 20:7; 27:43 — all in the context of Paul's missionary journeys. The word is deceptively simple: going out. Yet in Acts, every departure sets a new mission in motion. Leaving Thessalonica leads to Berea; leaving Berea leads to Athens; leaving one city opens the next city.
The exeimi of Paul's journeys embodies the missional principle of Acts: the gospel moves. It does not stay in one place, consolidated and comfortable. The Holy Spirit drives the messengers out — sometimes through persecution (Acts 8:1), sometimes through vision (Acts 16:9), sometimes through the natural rhythm of itinerant ministry. The church that stays put often stagnates; the church that goes out multiplies. The Kingdom of God is not a fortress — it is an advancing army, always departing to new territory.
