The Lord is very kind to the forgetful souls. He therefore comes Himself and leaves behind necessary instructions and also sends His good sons as representatives to call all the conditioned souls back to Godhead. Recently, within the memory of everyone, Lord Caitanya also appeared for the same purpose: to show special favor to fallen souls of this age of iron industry.
(Srimad Bhagavatam-----1:3:9-----purport).

The fallen and forgotten souls are detached from the transcendental loving service of the Lord. The living entities are parts and parcels of the Lord, and they are eternally servitors of the Lord. All the Vedic literatures, therefore, are put into systematic order for the benefit of the fallen souls, and it is the duty of the fallen souls to take advantage of such literatures and be freed from the bondage of material existence.
(Srimad Bhagavatam-----1:5:21-----purport).

The conditioned souls are forgetful souls in their relationship with the Lord, and thus a period of creation and the process of dissemination of Vedic knowledge are necessary activities of the Lord.
(Srimad Bhagavatam-----2:9:19-----purport).

The forgetful soul has no information of the spiritual creation, known as the sanātana-dhāma, but the temporary creation gives an idea of this original creation. The devotees of the Lord, therefore, make the best use of the bad bargain by utilizing the temporary creation in the service of the Lord.
(Light of the Bhagavata).

The material creation is meant for rebellious souls who are not prepared to accept subordination under the Supreme Lord. This spirit of false lordship is called false ego. It is manifested in three modes of material nature, and it exists in mental speculation only. Those who are in the mode of goodness think that each and every person is God, and thus they laugh at the pure devotees, who try to engage in the transcendental loving service of the Lord. Those who are puffed up by the mode of passion try to lord it over material nature in various ways. Some of them engage in altruistic activities as if they were agents appointed to do good to others by their mental speculative plans. Such men accept the standard ways of mundane altruism, but their plans are made on the basis of false ego. This false ego extends to the limit of becoming one with the Lord. The last class of egoistic conditioned souls—those in the mode of ignorance—are misguided by identification of the gross body with the self. Thus, all their activities are centered around the body only. All these persons are given the chance to play with false egoistic ideas, but at the same time the Lord is kind enough to give them a chance to take help from scriptures like Bhagavad-gītā and Śrīmad-Bhāgavatam so that they may understand the science of Kṛṣṇa and thus make their lives successful.
(Srimad Bhagavatam-----3:5:29-----purport).

The bhakti-vedāntas see that the people in general are wasting time in false sensuous things. Their business is to get the ignorant mass of people to reestablish their lost relationship with the Personality of Godhead. By such endeavor, even the most forgotten soul is roused up to the sense of spiritual life, and thus being initiated by the bhakti-vedāntas, the people in general gradually progress on the path of transcendental realization.
(Srimad Bhagavatam-----1:5:24-----purport).

A pure devotee cuts off the limited ties of affection for his family and widens his activities of devotional service for all forgotten souls. The typical example is the band of six Gosvāmīs, who followed the path of Lord Caitanya. All of them belonged to the most enlightened and cultured rich families of the higher castes, but for the benefit of the mass of population they left their comfortable homes and became mendicants.
(Srimad Bhagavatam-----1:8:41-----purport).
