Good Service, Good Reputation
1Tim 3:13 For those who have served well as deacons obtain for themselves a good standing and great boldness in the faith which is in Christ Jesus.
A good example of this is Acts 6 where Stephen was assigned a deacon's job of overseeing the distribution of food to the Hellenistic widows. And note also that Philip (not the apostle) was likewise assigned the task. Then suddenly the following chapters 7,8 focus on Stephen and Philip's ministry.
In fact I find it rather interesting that while the apostles claimed "It is not desirable that we should leave the word of God and serve tables." Acts 6:2, somehow Stephen and Philip found no problem in doing both these things. Thus God honors those who BOTH "wait on tables" (as Jesus himself had set the example in the Last Supper - John 13), AND minister the Word.
We note of Stephen it says, "And Stephen, full of faith and power, did great wonders and signs among the people. Then there arose some from what is called the Synagogue of the Freedmen (Cyrenians, Alexandrians, and those from Cilicia and Asia), disputing with Stephen. And they were not able to resist the wisdom and the Spirit by which he spoke." Acts 6:8,9
