Such hindrances, no matter how severe and insuperable they may at first seem, can and should be effectively overcome through the combined and sustained power of prayer and of determined and continued effort. For have not Bahá'u'lláh and 'Abdu'l-Bahá both repeatedly assured us that the Divine and unseen hosts of victory will ever reinforce and strengthen those who valiantly and confidently labour in their name? This assurance should indeed enable you to overcome any feeling of unworthiness, of incapacity to serve, and any inner or outer limitation which threatens to handicap your labours for the Cause. You should therefore arise, and with a heart filled with joy and confidence endeavour to contribute any share that is in your power toward the wider diffusion and greater consolidation of our beloved Faith.

Whatever the particular field of service you may choose, whether teaching or administrative, the essential is for you to persevere, and not to allow any consciousness of your limitations to dampen your zeal, much less to deter you from serving joyously and actively.
