There is the great commission given by Jesus.
Matthew 28 NIV
The Great Commission
16 Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. 17 When they saw him, they worshiped him; but some doubted. 18 Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.

The Great Commission
16 Now the eleven disciples went to Galilee, to the mountain which Jesus had designated. 17 And when they saw Him, they worshiped Him; but some doubted [that it was really He]. 18 Jesus came up and said to them, “All authority (all power of absolute rule) in heaven and on earth has been given to Me. 19 Go therefore and make disciples of all the nations [help the people to learn of Me, believe in Me, and obey My words], baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe everything that I have commanded you; and lo, I am with you always [remaining with you perpetually—regardless of circumstance, and on every occasion], even to the end of the age.”
