Srila Prabhupada, Srimad-Bhagavatam 1.1.20, Purport: In Bhagavad-gītā, the Lord says that His birth and deeds are transcendental and that anyone who is so fortunate as to know the transcendental nature of His birth and deeds will at once become liberated and eligible to return to the kingdom of God. So knowledge of the transcendental nature of the birth and deeds of Lord Śrī Kṛṣṇa is sufficient for liberation. In the Bhāgavatam, the transcendental nature of the Lord is described in nine cantos, and in the Tenth Canto His specific pastimes are taken up. All this becomes known as one's reading of this literature progresses. It is important to note here, however, that the Lord exhibited His divinity even from the lap of His mother, that His deeds are all superhuman (He lifted Govardhana Hill at the age of seven), and that all these acts definitely prove Him to be actually the Supreme Personality of Godhead.
