All Baha'i activities are for teaching the Cause

The cornerstone of the foundation of all Bahá'í activity is teaching the Cause. As ‘Abdu’l-Bahá has categorically proclaimed in His Will and Testament, ‘the guidance of the nations and peoples of the world’ is ‘the most important of all things’ and “Of all the gifts of God the greatest is the gift of Teaching’.
