In this Day deeds rather than words are necessary

O SON OF MY HANDMAID!
Guidance hath ever been given by words, and now it is given by deeds. Everyone must show forth deeds that are pure and holy, for words are the property of all alike, whereas such deeds as these belong only to Our loved ones. Strive then with heart and soul to distinguish yourselves by your deeds. In this wise We counsel you in this holy and resplendent tablet.

Bahá'u'lláh, The Hidden Words of Bahá'u'lláh, Persian No. 76


O SON OF DUST!
Verily I say unto thee: Of all men the most negligent is he that disputeth idly and seeketh to advance himself over his brother. Say, O brethren! Let deeds, not words, be your adorning.

Bahá'u'lláh, The Hidden Words, Persian No 5


What profit is there in agreeing that universal friendship is good, and talking of the solidarity of the human race as a grand ideal? Unless these thoughts are translated into the world of action, they are useless.

'Abdu'l Bahá, Paris Talks, p. 16



If you desire with all your heart, friendship with every race on earth, your thought, spiritual and positive, will spread; it will become the desire of others, growing stronger and stronger, until it reaches the minds of all men.

Do not despair! Work steadily. Sincerity and love will conquer hate. How many seemingly impossible events are coming to pass in these days! Set your faces steadily towards the Light of the World. Show love to all; 'Love is the breath of the Holy Spirit in the heart of Man'. Take courage! God never forsakes His children who strive and work and pray! Let your hearts be filled with the strenuous desire that tranquillity and harmony may encircle all this warring world. So will success crown your efforts, and with the universal brotherhood will come the Kingdom of God in peace and goodwill."

'Abdu'l Bahá, Paris Talks, p. 29
