"Now we ask you brothers, to respect those who work hard among you, who are over you in the Lord and who admonish you. Hold them in the highest regard in love because of their work."
1 Thessalonians 5:12-13a
I'm sure Paul must have found it awkward because I sure do, to address this matter. Paul is telling the believers that they should respect and hold in high regard those who the Lord has called to serve them. That of course includes himself. This is a request. It is not a mandate. Respect for those who serve the Lord in the ministry has greatly waned in recent decades. Some because some have behaved so wrongly, some because general respect is on the decline and some because the respect and regard for Christianity and Christians is in such decline. But as for believers, they should do just as Paul has asked.
Pastors and other ministry leaders should be given a respect because of the work they do. Sometimes you may respect the work more than the person, that is understandable. But, in general, Pastors, Missionaries, and other ministry workers should be held in high regard, as should those who serve. I know some Pastors, Missionaries and Ministry people, who because of their weaknesses, personalities or styles are difficult to respect, hold in any regard, even with love. But, because of their work and who they work for, they should be respected.
