December 5

Say: The appointed Day is come. This is the Springtime of benevolent deeds, were ye of them that comprehend. Strive ye with all your might, O people, that ye may bring forth that which will truly profit you in the worlds of your Lord, the All-Glorious, the All-Praised. 
- Baha’u’llah  (The Compilation of Compilation, vol. I, Huqúqu'lláh)
