The heart of our mission comes from
Jesus' words following his resurrection:

"All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age." (Matthew 28:18-20)

The direction of our mission comes from
His words preceding his ascension:

"You will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth." (Acts 1:8)
