It is not that other devotees who are less complete in knowledge are not dear to the Lord. The Lord says that all are magnanimous because anyone who comes to the Lord for any purpose is called a mahatma or great soul. The devotees who want some benefit out of devotional service are accepted by the Lord because there is an exchange of affection. Out of affection they ask the Lord for some material benefit, and when they get it they become so satisfied that they also advance in devotional service. But the devotee in full knowledge is considered to be very dear to the Lord because his only purpose is to serve the Supreme Lord with love and devotion. Such a devotee cannot live a second without contacting or serving the Supreme Lord. Similarly, the Supreme Lord is very fond of His devotee and cannot be separated from him.
