(One of the letters of Archbishop Périer, SJ, to Mother Teresa)

...Take a little time. If Our Lord wishes to work miracles in this case certainly He can do it, but we have no right to expect them and He does not work miracles without a very good reason. Be patient. By writing yourself now to Rome you might spoil the whole outcome of your petition. Perhaps the Very Reverend Mother general has written herself already. Just wait for a reply. Do not rush things, and do not expect others to rush them either. ... In due time the reply will come, remain quiet. Pray much and live intimately with Our Lord Jesus Christ asking for light, strength, decision; but do not anticipate HIS WORK. Try not to put anything of your own in all this. You are His instrument, nothing more. ... If Our Lord wants it to be done quickly He can arrange that; in the meantime being human creatures we must act according to our means.
