So can you guess what happens when a group of self-professed Christians joins together as a church—even a doctrinally robust, gospel-centered church? They will disagree about many matters. We should expect disagreements with fellow Christians about third-level matters, and we should learn to live with those differences. Christians don’t always need to eliminate differences, but they should always seek to glorify God by loving each other in their differences. Understanding what the conscience is and how it works helps us do that.
