Srila Bhaktivedanta Svami Prabhupada spoke on the glories of Srila Rupa Gosvami:

Śrīla Rūpa Gosvāmī is the confidential servant of Śrī Gaurasundara, the most munificent avatāra who mercifully appeared in the age of Kali (karuṇaya-avatīrṇaḥ kalau). Who but such an intimate servant can understand which mood appears in the heart of Mahāprabhu at what moment, and how that mood augments the hlādinī-śakti (internal pleasure potency) that resides there?No one has the power to understand the deep and diverse pastimes of Śrīman Mahāprabhu without bathing in the dust of the lotus feet of such an antaraṅgā (intimate, internal) associate. Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī Prabhu always prayerfully contemplated the lotus feet of those internal devotees, and in this way he proceeded in his service [of glorifying Mahāprabhu] without the slightest obstruction. He concludes every chapter of Śrī Caitanya-caritāmṛta with:

śrī-rūpa-raghunātha-pade yāra āśa
caitanya-caritāmṛta kahe kṛṣṇadāsa

Praying at the lotus feet of Śrī Rūpa and Śrī Raghunātha, always aspiring for their mercy, I, Kṛṣṇadāsa, narrate this Śrī Caitanya-caritāmṛta.We will understand the transcendental pastimes of Śrī Gaurasundara only when we receive the blessings of Śrīla Rūpa and Raghunātha.

For this reason Śrīla Rūpa Gosvāmī benedicted all

anarpita-carīṁ cirāt karuṇayāvatīrṇaḥ kalau
 samarpayitum unnatojjvala-rasāṁ sva-bhakti-śriyam
 hariḥ puraṭa-sundara-dyuti-kadamba-sandīpitaḥ
 sadā hṛdaya-kandare sphuratu vaḥ śacī-nandanaḥ

May the son of Śrīmatī Śacī-devī, Śrī Gaurahari, forever manifest spontaneously within the innermost core of your heart. Adorned with the radiant splendour of molten gold, He has descended (avatirṇaḥ) in the Age of Kali by His causeless mercy to bestow upon the world that which has not been given for a long time – the beauty of His own brilliantly radiant ujjvala-prema-rasa bhakti, service in the highest mellow of amorous love. (Vidagdha-mādhava 1.2)

Accomplish this Task

Karuṇaya-avatīrṇaḥ kalau – what kindness Śrī Śacīnandana-hari Gaurasundara has shown the jīvas overwhelmed by the age of Kali by mercifully descending at this time. The people of the world, however, are unable to comprehend His magnanimity, even today. Therefore, to assist us in understanding His purpose for descending, Śrī Gaurasundara Himself made a prediction and liberally ordered the residents of Bharat (India) to accomplish this task.

bhārata-bhūmite haila
 manuṣya janma yāra
 janma sārthaka kari’
 kara para-upakāra

Anyone who has taken a human birth in the land of India should make his life successful by striving for the highest benefit of all others. (Śrī Caitanya-caritāmṛta, Ādi-līlā 9.41)

All of the ācāryas in the line of Śrila Rūpa Gosvāmī have endeavoured tirelessly to inform everyone of this order of Mahāprabhu by writing unprecedented literatures. Commanded by Śrīla Bhaktivinoda Ṭhākura, oṁ viṣṇupāda Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura Prabhupāda proved most effective in his attempts to do this. If his qualified disciples had protected his line of thought and tried to inform the world about Śrīman Mahāprabhu, maybe by now they would have successfully preached the message of Śrī Gaurasundara in all corners of the globe.
