Mark 16:15

“Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit,

until the day when He was taken up to heaven, after He had by the Holy Spirit given orders to the apostles whom He had chosen,

but you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem, and in all Judea and Samaria, and even to the end of the earth.”

if indeed you continue in the faith firmly grounded and steadfast, and not moved away from the hope of the gospel, which you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister.
