prabhupada explained one time that basically if he is born a worm in the stomach of a devotee, basically this is what he is requesting that at least that time that way you can get little mahaprasad. The devotee should be taking prasad whereas by him even brahma he won’t even get mahaprasad. So actually the devotee of the lord is only perfect living being. All the good qualities of Krishna are also present in a devotee.
