Thus, just before his ascension to heaven, Jesus assured his disciples: “You will receive power when the holy spirit arrives upon you, and you will be witnesses of me both in Jerusalem and in all Judea and Samaria and to the most distant part of the earth. ” ​ — Acts 1: 8.
Seepärast tõotas Jeesus neile vahetult enne taevasse minekut: „Te saate jõu, kui püha vaim tuleb teie peale, ja olete siis minu tunnistajad nii Jeruusalemmas kui ka kogu Judeas ja Samaarias ning kuni maa kõige kaugema paigani ”.
