Commerce, agriculture and industry should not, in truth, be
a bar to service of the one true God. Indeed, such occupations are most potent
instruments and clear proofs for the manifestation of the evidences of one's
piety, of one's trustworthiness and of the virtues of the All-Merciful Lord.
(‘Abdu’l-Baha, from a Tablet; The Compilation of Compilations, vol. I,
Trustworthiness: A Cardinal
Bahá'í Virtue)
