Jesus told his followers to preach the Gospel to all nations.
The first Christians spread the Gospel wherever they went.
This document aims to encourage the continued spread of the Gospel

Many Christians, usually not Catholics, speak about "soul-winning".
As soon as such ChrItians are baptized,
they are encouraged to help other people know Jesus

Unfortunately this is not the experience of most Catholics.
Few Catholics are interested in "soul-winning"

Jesus, please help all Christians, especially Catholics,
to be more interested in spreading your Gospel
