溫和地反基, a reasonable question so lets take your topic to dicsussion.
"Do good works for the society" ? You know it is fantacy, since you do it for your own sake. Jesus asked us to "worship and glorify God", it is real and for our own benifits. God will live just about nicely without any of grudging worshipers.
Worship of God is good to your soul. Such a worship reaches truthfulness, joy and peace of your inner soul. It is for you and your own good.
