At the Fulcrum or End of the Lever

"No matter how good they [pastors] are at listening, hand-holding, and personal encouragement, if they cannot teach the word of God they are disqualified from the office/role of pastor/elder/overseer. ...

"Conversely, however, preachers who are nothing more than pulpiteers, who display few Christian graces that enable them to love people, work with people, listen humbly, exhort patiently, encourage graciously, and rebuke engagingly, are simply disqualified."
