Many understand as part of the Great Commission as well, “But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.” The Great Commission is enabled by the power of the Holy Spirit. We are to be Christ's witnesses, fulfilling the Great Commission in our cities (Jerusalem), in our states and countries (Judea and Samaria), and anywhere else God sends us (to the ends of the earth).
