Verily, God effecteth that which He pleaseth; naught can annul His Covenant; naught can obstruct His favour nor oppose His Cause! He doeth with His will that which pleaseth Him and He is powerful over all things! ... 
- ‘Abdu’l-Baha  (‘Tablets of Abdul-Baha Abbas, Vol. III’, quoted in a letter from the Universal House of Justice dated 9 March 1965)
