The second point which the Guardian wishes you to stress and
to keep always in mind is the necessity for every local and active member of
your committee to fully concentrate on the thorough study and understanding of
the spiritual and administrative principles of the Faith, as a necessary step
for active and fruitful teaching. You should first equip yourselves with the
necessary amount of knowledge about the Cause and then, and only then, try to
teach.

the Bahá'í Youth Committee; The Compilation of Compilations, vol. I, The
Importance of Deepening Our Knowledge and Understanding of the Faith)
