God sends His Prophets to “guide” us to the “light of true understanding” and to “ensure” our “peace and tranquility”

God's purpose in sending His Prophets unto men is twofold. The first is to liberate the children of men from the darkness of ignorance, and guide them to the light of true understanding. The second is to ensure the peace and tranquillity of mankind, and provide all the means by which they can be established.(Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 79)
