“earthly desires” & “Covenant of God”

Follow not, therefore, your earthly desires, and violate not the Covenant of God, nor break your pledge to Him. With firm determination, with the whole affection of your heart, and with the full force of your words, turn ye unto Him, and walk not in the ways of the foolish.... Break not the bond that uniteth you with your Creator, and be not of those that have erred and strayed from His ways.... 

- Baha’u’llah  (‘Gleanings from the Writings of Bahá'u'lláh; The Compilation of Compilations vol. I, The Covenant)
