Gita 6.39

TvadanyaH, sanshyasya, asya, chhetta, na, hi, uppadhyate ||39||

Translation: (Krishna) O Shri Krishna! (me) my (etat’) this (sanshyam’) doubt (asheshatH) completely (chhettum’) dispelling, only you (arhasi) are worthy (hi) because (tvadanyaH) anyone other than you (asya) this (sanshyasya) doubt (chhetta) who can dispel (na, uppadhyate) it is not possible to find. (39)

Gita 6.39: O Shri Krishna! Only you are worthy of completely dispelling this doubt of mine because it is not possible to find anyone else other than you who can dispel this doubt.

Meaning: The meaning of Verse 40 to 44 is that after experiencing the results of all the previous virtuous and evil deeds in heaven-hell, according to the previous nature of bhakti one develops yearning for bhakti, and then because of the previous nature only becomes deviated from the path i.e. because of not finding a Complete Saint never gets liberated.
