The harder you strive to attain your goal, the greater will be the confirmations of Bahá'u'lláh, and the more certain you can feel to attain success. Be cheerful, therefore, and exert yourself with full faith and confidence. For Bahá'u'lláh has promised His Divine assistance to everyone who arises with a pure and detached heart to spread His holy Word, even though he may be bereft of every human knowledge and capacity, and notwithstanding the forces of darkness and of opposition which may be arrayed against him. The goal is clear, the path safe and certain, and the assurances of Bahá'u'lláh as to the eventual success of our efforts quite emphatic. Let us keep firm, and whole-heartedly carry on the great work which He has entrusted into our hands.
