This is the symptom of a pure devotee. One should serve the spiritual master first. It is not that one should bypass the spiritual master and desire to serve the Supreme Lord.This is not the Principle for a Vaishnava. — Srimad Bhagavatam, 07.09.28.
Lord Shambhu (Shiva) the greatest of Vaishnavas.
Srimad Bhagavatam 12.13.16
The highest is the Vaishnava. Ideal vaishnava means he is a parama-hamsa. That means he is not envious from anybody. He is always thinking how to take others back to Godhead.
A Vaisnava is personally tolerant for the benefit of others. When he does not show his prowess, this does not mean that he is lacking in strength ; rather, it indicates that he is tolerant for the welfare of the entire human society.
The Vaisnava doesn't die because his teachings are always relevant and they are always true.
