Srimad-Bhagavatam: Canto 1 - Chapter 1 - Verse 25
तथायं चावतारस्ते भुवो भारजिहीर्षया ।स्वानां चानन्यभावानामनुध्यानाय चासकृत् ॥ २५ ॥
tathāyaṁ cāvatāras tebhuvo bhāra-jihīrṣayāsvānāṁ cānanya-bhāvānāmanudhyānāya cāsakṛt
Thus You descend as an incarnation to remove the burden of the world and to benefit Your friends, especially those who are Your exclusive devotees and are constantly rapt in meditation upon You.
It appears that the Lord is partial to His devotees. Everyone is related with the Lord. He is equal to everyone, and yet He is more inclined to His own men and devotees. The Lord is everyone’s father. No one can be His father, and yet no one can be His son. His devotees are His kinsmen, and His devotees are His relations. This is His transcendental pastime. It has nothing to do with mundane ideas of relations, fatherhood or anything like that. As mentioned above, the Lord is above the modes of material nature, and thus there is nothing mundane about His kinsmen and relations in devotional service.
