Back to school is a hectic time of year for everyone, not the least of which are teachers like me – I’m now entering my 12th year in public education. But besides getting my classroom organized and lesson plans finalized, a still small voice inside of me is reminding me to get my heart right too because I’m preparing to go on the mission field.
I didn’t always feel this way. When I started my teaching career, I had a pretty clear sense of my profession. I enjoyed my content area, was intrigued by the strategies involved in breaking down a concept, and rather quickly came to appreciate the relationships I formed with my students and colleagues. Teaching satisfied my professional ambitions, I thought that would be enough…but it wasn’t.
My Christian life has always been an important part of me, but without clearly realizing it at the time, I checked my faith at school doors each morning and picked it up again on my way out. This was not something I did intentionally, but that’s indeed the point: I wasn’t intentional at all. Apart from a few token gestures and general politeness, this huge part of me—my faith—was largely absent from my daily work. I become les satisfied, and after four or five years in, I started asking the Lord, “Is this all there is? Show me what it is I cannot see.”
And what He showed me changed me.
After his crucifixion and resurrection, just before he ascended to heaven, Jesus gave his followers their marching orders: if you really believe all you have seen, and if you really have a transformed life, then “go and make disciples” (Matt. 28:16-20). To me, these words were always either hypothetical or meant for another race of “Super-Christians,” like missionaries who would travel around the world or pastors who were paid to do this type of thing, not plain old “normal Christians” like me who work full-time secular jobs.
But the Lord opened my heart and mind to understand that every Christian shares in this missional calling to make disciples because we are all Christ’s followers. His final command wasn’t just for one group of men; it was for all men and women who would come to follow him. There were indeed disciple-making opportunities all around me, starting with my work—that place I spend 40+ hours a week.
More than a career, I realized that I have a calling – to go to school and share the light of Jesus Christ with every student, colleague, or administrator with whom I interact. Yes, I am a public school teacher, which of course does limit my words to a certain extent, but armed with an understanding of my higher calling, I am intentional now in an entirely new way. Like many teachers, I spend a great deal of time preparing my lesson plans and grading papers, but now my challenge each day is to spend time with the Lord to prepare my heart before I enter my workplace, i.e., the mission field. I’ve got to pray for my students and colleagues with a genuine heart for their salvation; I’ve got to seek wisdom for boldness to know when to speak and prudence for when to stay silent; I’ve got to ask for a caring heart to earn the right to be heard; I’ve got to pray for opportunities outside of the classroom to further deepen these relationships.
I am certainly not perfect in that daily preparation? Sometimes that sneaky alarm clock seems to snooze itself, but the Lord doesn’t usually let me get to far without reminding me of the need to be more intentional in preparation and prayer.
Dear believer, if you call yourself a follower of Christ, your calling is the same as mine, and it’s the most important thing we will ever do. How does your career empower you in that calling? Do you work construction? Are you working in an office or restaurant? Are you lawyer, doctor, merchant, or chef? The essential truth here has nothing to do with the career itself. The truth is that every Bible-believing Christian is a missionary wherever he or she goes, and I write today to encourage you to step into that calling, to ask the Lord to strengthen you in your resolve to be intentional in prayer and service to those you work with each day. So that today, or tomorrow, or the next day when a colleague or client may ask you about the hope you seem to have and that you would be prepared to give account of how the Lord has transformed your life.
