Having a secular society with an interest in spirituality has a lot of avenues to explore. The evaluations and judgments have already started. The early church received its start and even thrived in societies strongly influenced by Judaism, secularism, and pagan religions. There appears little reason why churches today can't do the same in a secular setting. I believe we have only two options.
Churches can either curse the darkness or light a lamp.
It's not healthy nor beneficial to bemoan our cultural conditions and withdraw into the four walls of our facilities. Rather, the second option is the better one. Churches need wisdom like that possessed by the tribe of Issachar who joined their forces with King David. Church leaders should study and understand our times and cultures. They should see the opportunities and light a lamp so that people can find the Lord and grow in the grace and knowledge of Jesus Christ.
