One should certainly give up all other propositions and surrender to Krsna. Krsna will then immediately take charge and relieve one of the results of past sinful life (aham tvam sarva-papebhyo moksayisyami ma sucah) - BG 18.66

Srimad-Bhagavatam

SB Canto 5

One who has taken birth in the land of Bhārata-varṣa has a full opportunity to study the direct instructions given by Kṛṣṇa in Bhagavad-gītā and thus finally decide what to do in his human form of life. One should certainly give up all other propositions and surrender to Kṛṣṇa. Kṛṣṇa will then immediately take charge and relieve one of the results of past sinful life (ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi mā śucaḥ (BG 18.66)). Therefore one should take to Kṛṣṇa consciousness, as Kṛṣṇa Himself recommends.

SB 5.19.23, Translation and Purport

A short life in the land of Bharata-varṣa is preferable to a life achieved in Brahmaloka for millions and billions of years because even if one is elevated to Brahmaloka, he must return to repeated birth and death. Although life in Bhārata-varṣa, in a lower planetary system, is very short, one who lives there can elevate himself to full Kṛṣṇa consciousness and achieve the highest perfection, even in this short life, by fully surrendering unto the lotus feet of the Lord. Thus one attains Vaikuṇṭhaloka, where there is neither anxiety nor repeated birth in a material body.

This is further confirmation of the statement given by Lord Caitanya Mahāprabhu:

bhārata-bhūmite haila manuṣya-janma yāra

janma sārthaka kari' kara para-upakāra

(CC Adi 9.41)

One who has taken birth in the land of Bhārata-varṣa has a full opportunity to study the direct instructions given by Kṛṣṇa in Bhagavad-gītā and thus finally decide what to do in his human form of life. One should certainly give up all other propositions and surrender to Kṛṣṇa. Kṛṣṇa will then immediately take charge and relieve one of the results of past sinful life (ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi mā śucaḥ (BG 18.66)). Therefore one should take to Kṛṣṇa consciousness, as Kṛṣṇa Himself recommends. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru: (BG 18.65) "Always think of Me, become My devotee, worship Me and offer Me obeisances." This is very easy, even for a child. Why not take this path? One should try to follow the instructions of Kṛṣṇa exactly and thus become fully eligible to be promoted to the kingdom of God (tyaktvā dehaṁ punar janma naiti mām eti so'rjuna (BG 4.9)). One should go directly to Kṛṣṇa and engage in His service. This is the best opportunity offered to the inhabitants of Bhārata-varṣa. One who is fit to return home, back to Godhead, is no longer liable to the results of karma, good or bad.
