…one of the greatest and most fundamental principles of the
Cause of God is to shun and avoid entirely the Covenant-breakers, for they will
utterly destroy the Cause of God, exterminate His Law and render of no account
all efforts exerted in the past. O friends! It behoveth you to call to mind
with tenderness the trials of His Holiness, the Exalted One and show your
fidelity to the Ever-Blest Beauty. The utmost endeavor must be exerted lest all
these woes, trials and afflictions, all this pure and sacred blood that hath
been shed so profusely in the Path of God, may prove to be in vain.
- ‘Abdu'l-Baha (‘Baha'i World Faith’)
