There are numerous passages in the New Testament that use the Greek term diakonos and its cognates (Rom. 16:1, Eph. 6:21, Col. 1:7, Col. 4:7, Phil. 1:1, Acts 6:1-6). The word “deacon” simply means “servant” or “minister.” In one sense, all God’s people are called as “ministers” or “deacons.” However, there is an official role for some to share that is designated with the title of “deacon.” Although many passages give us a sense that a deacon is a mature servant of the local church, the clearest passage on the qualifications and call of deacons is 1Timothy 3:8-13.
Deacons likewise must be dignified, not double-tongued, not addicted to much wine, not greedy for dishonest gain. They must hold the mystery of the faith with a clear conscience. And let them also be tested first; then let them serve as deacons if they prove themselves blameless. Their wives likewise must be dignified, not slanderers, but sober-minded, faithful in all things. Let deacons each be the husband of one wife, managing their children and their own households well. For those who serve well as deacons gain a good standing for themselves and also great confidence in the faith that is in Christ Jesus.
What is clear from this passage is that the deacon occupies a significant office in the church. The qualifications are high, as is the promise of reward. As one of the two offices of the New Testament church, deacons are esteemed servants. This is a significant role, given by God for the good of his church.
