Jesus came and told his disciples, "I have been given complete authority in heaven and on earth. ¹⁹Therefore, go and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit. ²⁰Teach these new disciples to obey all the commands I have given you. And be sure of this: I am with you always, even to the end of the age." (Matthew 28:18 - 20)

⁷Jesus said to them: "It is not for you to know the times or dates the Father has set by his own authority. ⁸But 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."  (Acts 1:7, 8)
