Several key ideas from this article:

Spreading the Good News is often a matter of
two steps forward and one step back

The spreading the Good News must be adapted
to local cultures and situations

"Missions" is the term usually given to the task of preaching the Gospel
and planting the Church among peoples or groups who do not yet believe in Christ

Circumstances are sometimes such that, for the time being,
there is no possibility of expounding the Gospel directly.
Then missionaries can and must at least bear witness to Christ
by charity and by works of mercy, with all patience, prudence and great confidence. Thus they will prepare the way for the Lord and make Him present.

Great damage is done to the spread of the Gospel
by the lack of unity among Christians.
Ecumenism is a priority for better spreading of the Gospel

Jesus, please especially bless and protect
all Gospel workers in places
where your Good News cannot be proclaimed openly!
