Acts 1:8 records Jesus’ final words to His disciples before His ascension. In this verse, Jesus promises that they will receive power from the Holy Spirit, who will come upon them to equip and empower them. This empowerment is not for personal gain but for the purpose of being witnesses of Jesus Christ. Their testimony was to begin in Jerusalem(where they were currently located), extend to Judea and Samaria (neighboring regions, including those culturally and religiously different from them), and ultimately reach to the ends of the earth.
