The question that is often posed to many Christians as they begin to mature is, "What is your calling?" Every Christian has a calling and no calling is more important than another. As a matter of fact, many times it is those callings/jobs that no one really takes notice of that make the most impact. Like those called to help and to serve. These people tirelessly work behind the scenes making sure that things run smoothly and never hesitate to take on the jobs no one else will do only to have their recognition postponed until we see Jesus. Then you have the prayer warriors who are in their closets praying while others sleep and no one realizes the battles they fight, however, the victories they win are experienced by the whole body. No, not everyone is "called" to preach and teach and those who are, are nothing without the rest of the body. As you read Paul's letters, you find many list of people who supported him and their names would have been lost to history if not for Paul's commendations.
We go through many things and probably will make many mistakes in trying to discover our calling. Some possible steps in discovering what God has intended you do may include the following. First, we must discover the heart of God. Apart from that anything else we do will be done out of obligation or with the wrong motives and there will be little or no spiritual benefit from it. God's motive for everything He did was love, and by discovering who God is and how God moves we begin to scratch the surface of why He does the things He does. Jesus expressed God's heart when He was moved with compassion upon seeing all the people following Him. He stated that the were like sheep without a shepherd. Because of that compassion, He was moved to meet their needs. What moves God should move us. That leads us to the second step, and that is being sensitive to the needs of others. We can't go around so self absorbed that we don't take notice of the condition of those around us. They are put in path for a reason, so that through us, they may come to know God or be encouraged by Him. Thirdly, we must be faithful in the "small things." In saying that, we must realize that there are no small things in the eyes of God. Visiting the widow next door is just as important as preaching to a thousand people. Fourth, we must let God bring promotion. ". . . love," wrote Paul, "does not parade itself, is not puffed up . . . [and] does not seek its own. . ." Someone truly motivated by the heart of God is not looking for the next position or looking to make themselves known, they are looking to serve. Lastly, we must get to work. Many times in scripture we are encourage to work or to occupy till Christ comes. Also, you find in scripture, many times that God calls those who are doing something.
