Courage

In the treasuries of the knowledge of God there lieth concealed a knowledge which, when applied, will largely, though not wholly, eliminate fear. This knowledge, however, should be taught from childhood, as it will greatly aid in its elimination…. Whatever decreaseth fear increaseth courage.

Bahá’u’lláh, Epistle to the Son of the Wolf, p. 32

It is evident that nothing short of this mystic transformation could cause such spirit and behaviour, so utterly unlike their previous habits and manners, to be made manifest in the world of being. For their agitation was turned into peace, their doubt into certitude, their timidity into courage. Such is the potency of the Divine Elixir, which, swift as the twinkling of an eye, transmuteth the souls of men!

Bahá’u’lláh, The Kitab-i-Iqan, p. 156-157

The source of courage and power is the promotion of the Word of God, and steadfastness in His Love.

Bahá’u’lláh, Tablets of Bahá’u’lláh, p. 155

Whatever decreaseth fear increaseth courage.

Bahá’u’lláh, Epistle to the Son of the Wolf, p. 32

. . . when a band of men are besieged in some place where all avenues and roads are stopped and all hope of deliverance is cut off they will assuredly defend themselves desperately and display bravery and courage.

‘Abdu’l-Bahá, A Traveller's Narrative, p. 23

Consider thou the lives of the former sanctified souls; what tests have they not withstood and what persecutions have they not beheld; while they were surrounded with calamities they increased their firmness and while they were overwhelmed with tests they manifested more zeal and courage. Be thou also like unto them.

‘Abdu’l-Bahá, Tablets of ‘Abdu’l-Bahá v2, p. 302
