The servants of the Lord are actually the servants of society. They are interested in imparting knowledge of the relationship of the living being with the Supreme Lord, the activities in that transcendental relationship and the ultimate goal of human life. That is the real knowledge which can help society achieve the real aim of human welfare.
Without becoming a devotee of the Lord, one cannot perfect one's human life. The perfection of human life is to be elevated to the spiritual world, where there is no birth, no death, no disease and no old age. Without this aim, any amount of material advancement in so-called comforts can only bring the defeat of the human form of life.
Devotee should only serve the Supreme Personality of Godhead. As Lord is the protector of His Devotees, he takes care of everything. Devotee has nothing to worry about.
Do your best to serve Krishna and He will give you required intelligence to cope with disturbing situations.
