[Canto 4, Ch. 22]
rājā uvāca —the King said;  kṛtaḥ —done;  me —unto me;  anugrahaḥ —causeless mercy;  pūrvam —formerly;  hariṇā —by the Supreme Personality of Godhead, Lord Viṣṇu;  ārta-anukampinā —compassionate for persons in distress;  tam —that;  āpādayitum —to confirm it;  brahman —O  brāhmaṇa ;  bhagavan —O powerful one;  yūyam —all of you;  āgatāḥ —have arrived here.
TRANSLATION
The King said: O  brāhmaṇa , O powerful one, formerly Lord Viṣṇu showed me His causeless mercy, indicating that you would come to my house, and to confirm that blessing, you have all come.
PURPORT
When Lord Viṣṇu appeared on the great arena of sacrifice at the time when King Pṛthu was performing a great sacrifice ( aśvamedha ), He predicted that the Kumāras would very soon come and advise the King. Therefore Pṛthu Mahārāja remembered the causeless mercy of the Lord and thus welcomed the arrival of the Kumāras, who were fulfilling the Lord's prediction. In other words, when the Lord makes a prediction, He fulfills that prediction through some of His devotees. Similarly, Lord Caitanya Mahāprabhu predicted that both His glorious names and the Hare Kṛṣṇa  mahā-mantra  would be broadcast in all the towns and villages of the world. Śrīla Bhaktivinoda Thākura and Śrīla Bhaktisiddhānta Sarasvatī Prabhupāda desired to fulfill this great prediction, and we are following in their footsteps.
Regarding His devotees, Lord Kṛṣṇa told Arjuna,  kaunteya pratijānīhi na me bhaktaḥ praṇaśyati : "O son of Kuntī, declare it boldly that My devotee will never perish." (Bg. 9.31) The point is that the Lord Himself could declare such things, but it was His desire to make the declaration through Arjuna and thus doubly assure that His promise would never be broken. The Lord Himself promises, and His confidential devotees execute the promise. The Lord makes so many promises for the benefit of suffering humanity. Although the Lord is very compassionate upon suffering humanity, human beings are generally not very anxious to serve Him. The relationship is something like that between the father and the son; the father is always anxious for the welfare of the son, even though the son forgets or neglects the father. The word  anukampinā  is significant; the Lord is so compassionate upon the living entities that He comes Himself into this world in order to benefit fallen souls.
