A pure devotee has no demand from the Lord. His only concern is to serve the Lord sincerely and seriously and he is not at all concerned about what will happen in the future. — Srimad Bhagavatam, 04.09.29.
Devotees are not impressed by the poverty or wealth in material sense in any way; what impresses is devotion.
A devotee is surrendered to whatever Krishna wants. If Krishna wants him to take birth again, he will take, but he prays to remain in the association of devotees.
If an ordinary man does not eat, he will grow weak and die. Similarly, if a devotee does not taste the transcendental pastimes of Lord Chaitanya Mahaprabhu and Lord Krishna, he will gradually weaken and die spiritually.
