We can expect difficulties and hardships when attempting to serve the Cause of God

O maid-servant of God! Everything of importance in this world demands the close attention of its seeker. The one in pursuit of anything must undergo difficulties and hardships until the object in view is attained and the great success is obtained. This is the case of things pertaining to the world. How much higher is that which concerns the Supreme Concourse! That Cause involves every favor, glory and eternal bliss in the world of God. The seeker after the great guidance and eternal happiness necessarily will encounter difficulties. He must be patient under such circumstances. The chosen believers of the past quaffed the chalice of suffering and sank deep in the ocean of trials until they attained to that blessed station and sublime beatitude. (‘Abdu'l-Baha, Tablets of Abdu'l-Baha v2, p. 265)
