A devotee's only desire is to please Krishna and nothing else but Krishna's pleasure. Hence Krishna, in order to please his devotees, shows his pleasure.
One, who worships the Supreme Lord and His holy name with undivided faith, knowing them to be identical, is considered an elevated, first class devotee, even if he does not understand the intricacies of his own spiritual identity.
Whatever a devotee experiences he should consider to be an expansion of Krishna. Thus seeing everything that exists within creation as the body of the Supreme Lord Hari, the devotee should offer his sincere respects to the entire expansion of the Lord's body.
Any devotee who has developed genuine love for Krishna can also explain the truth about Krishna because Krishna helps such sincere devotee seated in his heart.
This protection is offered to a devotee even from the very beginning of his devotional service. Kaunteya pratijanihi na me bhaktah pranasyati (Bhagavad Gita 9.31). If one simply begins devotional service, he is immediately protected by the Supreme Personality of Godhead. This is also confirmed in Bhagavad Gita (18.66) : aham tvam sarva papebhyo moksayisyami. Protection begins immediately. The Lord is so kind and merciful that He gives the devotee proper guidance and all protection, and thus the devotee very peacefully makes solid progress in Krishna Consciousness without outward disturbances. A serpent may be very angry and ready to bite, but the furious snake is helpless when faced by a blazing fire in the forest. Although an enemy of a devotee may be very strong, he is compared to an angry serpent before the fire of devotional service.
Krishna takes a special appreciation for His devotees who are engaged in risking for His preaching work and He will give you special care and guidance at all times because you are sincerely trying to serve Him in this way.
