The final instruction of Jesus to his disciples, to make disciples of all nations
The Great Commission, most famously found in Matthew 28, is the final instruction of Jesus to his disciples:
18 And Jesus came and said to them, “All authority in heaven and on earth has been given to me. 19 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, 20 teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.” (ESV)
