The Lord comes Himself in different incarnations, or He sends His confidential servants as sons or His associates or ācāryas to reclaim the conditioned souls.
(Bhagavad-Gita--introduction).

The opinions of the demigods are valuable because the demigods are authorized to hold positions in the affairs of universal management. They are appointed by the Lord as His confidential servants.
(Srimad Bhagavatam---3:5:39---purport).

The devotees of the Lord, who are all confidential servitors, are sometimes perplexed in the discharge of their respective duties, but they are never discouraged.
(Srimad Bhagavatam---3:13:17---purport).

The Lord is always compassionate towards the fallen souls of this material world, and therefore He comes Himself or sends His confidential servants to deliver them.
(Srimad Bhagavatam---3:29:6---purport).

A devotee who is a most confidential servant of the Lord never does anything for his personal account, but does everything for the satisfaction of the Supreme Lord.
(Srimad Bhagavatam---3:29:33---purport).

The spiritual master is honored as much as the Supreme Lord because he is the most confidential servitor of the Lord. This is acknowledged in all revealed scriptures and is followed by all authorities." The supreme Vaiṣṇava is the spiritual master, and he is nondifferent from the Supreme Personality of Godhead.
(Srimad Bhagavatam---4:23:31---purport).

It is therefore a truth that the Supreme Personality of Godhead Himself or His confidential servants manifest themselves by their own potency and without any help from this material world.
(Renunciation Through Wisdom).
