As a full-time vocational church director handling discipleship and a frequent writer for a Christian website on the topics of faith, family, leadership and culture, my job honours God. But what doesn't follow is that, because what I do is ministry, my job gives more honour to God than any other job.
The call to full-time ministry is a noble calling, but it's not a calling that only vocational ministers, pastors, prophets and evangelists are called into. Remember that we are all in full-time ministry as long as what you do is for the honour and glory of God and exists to serve other people in a way that impacts their way of living.
The word ministry in Greek is the word 'diakonia,' which more directly translates as service. When you serve others, you are in ministry. In that sense, any profession can be a ministry. Whether you're a doctor, engineer, restaurant waiter, street sweeper or chauffeur, if you do what you do to serve people as an expression of your love to them as God has loved you and if you do it as worship to God, you're very well ministering to people.
I can count various opportunities where people have uplifted and encouraged me through their valiant and excellent acts of service. The way a store clerk smiles and gives excellent customer service, the way a barista does his or her work heartily as unto the Lord and the way our house help stewards my home with extreme excellence all bless my heart and spirit as much as any minister would.
Your profession, given that it is moral and legal, is God's call over your life and God tends to use you in that avenue. Remember that David was called to be a politician, Gideon was called to be a soldier, Job was called to be a businessman and Mary was called to be a mother, and God used all of them to bring glory to Him and let His work be done here on earth.
1 Corinthians 7:17 says, "Only let each person lead the life that the Lord has assigned to him, and to which God has called him" (ESV). What God has called you to do—whether it's work in the marketplace or in church affairs—is ministry. While God does give some believers the call to vocationally work to maintain church community and equip believers to minister, it's everyone's job to be God's hands and feet all throughout the world.
No job is more noble than another. What makes a job sacred and called is when it is used for God's greater glory and for the service of His people.
