17 And when they saw Him, they fell down and worshiped Him; but some doubted.
18 Jesus approached and, breaking the silence, said to them, All authority (all power of rule) in heaven and on earth has been given to Me.
19 Go then and make disciples of all the nations, baptizing them into 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 behold, I am with you all the days (perpetually, uniformly, and on every occasion), to the [very] close and consummation of the age. Amen (so let it be).

And surely I am with you always, to the very end of the age.”
