Today the greatest of all affairs in the Cause is firmness and
steadfastness. A tree will not give fruit unless it be firmly rooted. A
foundation will not last unless it be firm. There is nothing in this world of
man greater than firmness. A soul who is firm will become a son of the Kingdom
of God and will be confirmed with the power of the Holy Spirit. - ‘Abdu’l-Baha (‘Tablets of ‘Abdu’l-Baha, vol. 2)
