First of all what do we think of when we think of ministry? Do we think of a Pastor? A missionary? Ministry can be something big and full time, but it can also be quite small.
The ministry in our day has taken on more of a vocational meaning as we call pastors “ministers” to full-time service. Pastors do spend their lives in the ministry, they do minister to others, and they can rightly be designated as ministers, but pastors are not the only ones who are to be involved in ministry. From the early New Testament churches to the churches of our day, each Christian should be in the ministry of helping others (see Romans 12:3-8, 10-13; 2 Timothy 2:24-26).
“Ministry” is from the Greek word diakoneo, meaning “to serve” or douleuo, meaning “to serve as a slave.” In the New Testament, ministry is seen as service to God and to other people in His name. Jesus provided the pattern for Christian ministry—He came, not to receive service, but to give it (see Matthew 20:28; Mark 10:45; John 13:1-17). Christians are to minister to others out of their devotion to Christ and their love for others, whether the other people are believers or unbelievers. Ministry to others should be impartial and unconditional, always seeking to help others as Jesus would.
In its essence, this is what ministry is all about – playing your part in helping God’s plan and purpose to be outworked in other people’s lives
So by helping your neighbor, visiting a senior in a home, being a Godly wife and mother, serving at church in any capacity, is all ministry.
