Finding our Welfare in the Welfare of our Cities

In the following verse God instructs the Israelites who are living in exile to seek the welfare of the city of their captures. I don't think much about serving in my city but these verse is an intriguing one to consider.
Jeremiah 28:4 “Thus says the Lord of hosts, the God of Israel, to all the exiles whom I have sent into exile from Jerusalem to Babylon: 5 Build houses and live in them; plant gardens and eat their produce. 6 Take wives and have sons and daughters; take wives for your sons, and give your daughters in marriage, that they may bear sons and daughters; multiply there, and do not decrease. 7 But seek the welfare of the city where I have sent you into exile, and pray to the Lord on its behalf, for in its welfare you will find your welfare.
It raises the question in my mind, "What involvement can I have in the betterment of my city that will bring God glory and increase the pleasure I feel each day?"
