Some people doubt that when the devotees of the supreme Lord are in trouble, does the supreme Lord himself come to rescue them or is it just imagination?
Parampujyapad Srila Bhaktivedanta Swami Maharaj says that the Lord is very kind to the living beings of this world because all living beings are His children.
Sri Krishna says in the Bhagavad Gita, “sarva-yoniṣhu kaunteya mūrtayaḥ sambhavanti yāḥ
tāsāṁ brahma mahad yonir ahaṁ bīja-pradaḥ pitā” (14/4).
That is, Lord Krishna says – ‘It is right that all the living beings in this world are getting happiness and sorrow according to their deeds. I am the father of all and I personally come to this earth to make all living beings know their real position.’
In different eras, God appears in his different forms, and also incarnates in every era to give darshan to his devotees and protects them. We just have to experience them.
