The real Christian life is lived on a steady diet of obedience and service.
We believe in and teach what is traditionally known as the Protestant work ethic. Many in America do not even know what that means either in context or function.
Some Christians practice the Protestant talk ethic. All show and no go.
There is no basis in Scripture for failure to act, move, or go. Christians are created to be movers and shakers in this world by living active, significant, and strategic lives.
How could a light be anything less?
