None at all. Sunrise and sunset are for the benefit of mankind. It enables man to discharge his duties during the day and rest during the night. Similarly, every act of God is for the benefit of mankind, not for His own. As the rays emanate from the sun, so does Nature originate from God.
Nature is the reservoir of power and energy.
It is said that the workings of Divinity are most wonderful. Every educated person should engage himself or herself in selfless service to society with humility and a pure heart. All academic distinctions or even observance of spiritual practices are of no use if there is no love in the heart. Love and compassion are inherent in every person. Each has to share this love with others.
