Evangelists are also to teach other believers how to lead people to the Lord Jesus. To pilot, guide, or steer as one steers a ship. To preside over the assembly and guide the proceedings. In order to preserve order in Christian meetings the person in charge should know how to direct the course of events towards a spiritual goal as led by the Spirit. Perhaps this also includes setting the pace, imparting direction and goals in a ministry since sheep are lazy and helpless and prone to wander off course.
Most people like to follow a good leader.
God's leaders are not only visionary they lead by serving. Also anyone's faith grows as it is exercised. Not supernatural utterances from God. The ability to sum up lots of information or pieces of knowledge so as to give a clear concise overview. The ability to make wise choices and decisions at critical forks in the road.
