The word “ministry” or “minister” found in the New Testament comes from the Greek word “diakonos”. It is also translated as “work”, “helper”, “servant” or “deacon”. It includes most of the work or service of the Church, whether it is feeding the hungry, picking up garbage at the church parking lot, preaching the Word or serving as an Usher or Board Member.
Ministry may be “up front” or it may be “behind the scenes”. As Peter wrote about he who speaks (up front) or he who serves (behind the scenes). As each has received a gift, use it to serve one another, as good stewards of God’s varied grace: whoever speaks, as one who speaks oracles of God; whoever serves, as one who serves by the strength that God supplies—in order that in everything God may be glorified through Jesus Christ. 1 Peter 4:10c-11a ESV
