1 Timothy 3:8-12
Deacons are equally qualified with elders in terms of character and spiritual life. The one difference between their qualifications is that an elder must be able to teach, but the deacon does not need to have this ability. The elders oversee the work of those who serve the Lord, and they are assisted in their work by deacons. The qualifications for deacons can be divided into two categories: personal character and spiritual character.
The role of the deacon is to provide pastoral care and serve the local body of believers. The church needs deacons to provide ecclesiastic and logistical support and duties so that the pastors and elders can focus on the word of God and prayer (Acts 6:3-4).
The office of deacon is a servant-leader ministry. Decaons are individuals nominated by elders and presented to the church body for approval, and if they accept the role they commit to:
Deacons follow Christ's example of service by serving the church body; in doing so, they are not only serving one another, but serving Christ Himself.
“42...You know that those who are considered rulers of the Gentiles lord it over them, and their great ones exercise authority over them. 43 But it shall not be so among you. But whoever would be great among you must be your servant, 44 and whoever would be first among you must be slave of all. 45 For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.”
Mark 10:42-45
