Why is Paul considered to be a great leader in the early church?

All christians are told to take the gospel to others

Mat 28:19 Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,

Mat 28:20 teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age." Amen.

Paul dedicated his life to doing this
