As Christians we want to please God, so we often find ourselves asking: What is God calling me to? Am I supposed to be a teacher, a doctor, an artist, a wife, or a stay at home mother? Should I be a missionary to a foreign land?
Our calling matters to God. He is the One who created it even before the dawn of time. The concept of calling goes much deeper than just defining it as our work. God’s calling is to a life in which every facet of our lives is united in God’s purposes for the world.
Our primary calling, meaning the call that is more important than any other, is to belong to Him, to be His child, and participate in His redemptive work in the world. This is to be lived out in where we work, in relationships we have, and in everything that we do.
Let's take a look at a passage where we can see what is meant by calling.
"I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, eager to maintain the unity of the Spirit in the bond of peace. There is one body and one Spirit - just as you were called to the one hope that belongs to your call - one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all. But grace was given to each one of us according to the measure of Christ's gift." Ephesians 4:1-7 ESV
Notice that there is no reference in this passage to a career. Career is NOT the calling. Rather, Paul writes how we are to live because of our calling - how we are to live because we belong to Christ. I should take a moment here to say that there are references where God does call specific people to specific tasks, but I believe that is the exception rather than the norm. To look at calling in that sense you can read the accounts about Moses, David, John the Baptist and Paul (Also consider looking at more of Paul’s letters for a broader biblical definition of calling).
If you are convicted to do something specific, consider if it is from God. Test it by His Word. Often we are torn between two decisions and then ask the question "which am I called to?" God has gifted us with the ability to consider and act on opportunities before us. Our purpose is not our job. It is a way in which we live out our purpose as children of God. So can you be a teacher, a doctor, an artist, a wife, a mother, or a missionary? Yes! But you are first a child of God and the ways in which He has manifested His character in you will help you to figure out how you should live out your life as His child.
