For one who explains the supreme secret to the devotees, devotional service is guaranteed, and at the end he will come back to Me.
PURPORT
Generally it is advised that Bhagavad-gita be discussed amongst the devotees only, for those who are not devotees will neither understand Krishna nor Bhagavad-gita. Those who do not accept Krishna as He is and Bhagavad-gita as it is should not try to explain Bhagavad-gita whimsically and become offenders. Bhagavad-gita should be explained to persons who are ready to accept Krishna as the Supreme Personality of Godhead. It is a subject matter for the devotees only and not for philosophical speculators. Anyone, however, who tries sincerely to present Bhagavad-gita as it is will advance in devotional activities and reach the pure devotional state of life. As a result of such pure devotion, he is sure to go back home, back to Godhead.
(Bhagavad-gita As It Is 18.68 and Bhaktivedanta Purport)
There is no servant in this world more dear to Me than he, nor will there ever be one more dear.
(Bhagavad-gita As It Is 18.69)I
