A deacon is someone pretty much like me and like you. They cannot walk on water; they have foibles and peccadilloes, strengths and weaknesses. In short, deacons are human beings.
Nowhere in the Bible does it say that perfection is required. But there are qualifications and characteristics that are necessary. First and foremost, the individual must have a personal relationship with Jesus Christ, i.e., he must be a Christian. Part of the ordination service today will be testimonies of their faith given by our new deacons.
Faithfulness is, I believe, the next priority for a deacon. No matter how gifted or capable, if the individual isn't faithful in attendance then what kind of service can they render?
The New Testament lists other qualifications: controlled by the Holy Spirit, having a good reputation, men of dignity, not double-tongued or addicted to much wine, not fond of sordid gain, above reproach, husbands of only one wife and good managers of their children and their households.
Deacons are men who are under construction. And the building process won't be completed until Jesus comes or we go to be with Him.
Pray for your deacons, love them, and honor them in the Lord for the sake of their work. They will be blessed, your life will be enriched and the church will grow spiritually and in numbers.
