The first consideration is the needs of the world. The single strongest indicator of what God wants you to do is probably your awareness of what needs to get done to make the world more like what God intends. This doesn’t necessarily mean huge, global problems, but simply anything in the world that needs to be done. Earning a living to support yourself and your family is one example mentioned in the Bible:

Another biblical example is working so as to meet the needs of individuals around you besides your family:

Working to serve the good of the larger society is also a biblical imperative:

Of course, it is impossible for you to meet every need of the world, so you have to narrow it down a bit. Start with needs for which you are personally responsible, such as raising your children or paying your debts. Beyond that, pay attention to needs that you are in a good position to meet, or that few other people are willing to address, or that you find especially pressing. You might be in a good position to run for an elected office in your own city or town, for example, compared to moving away to find work. On the other hand, you might be one of the few people willing to document human rights abuses in a country half way around the world. Or you might become convinced that teaching troubled youth is more pressing than joining a band. Moreover, it might become clear that something in your life other than your job or career is the most important way you are helping to meet the world’s needs. It would be pointless to get a job counseling troubled youth, only to neglect your own children.

The point is that God has given everyone the ability to recognize something of what the world needs. He seems to expect us to notice it and get to work, rather than waiting for a special call from him. There is no biblical formula for translating the needs of the world into a precise job calling. That’s why you need to seek God’s guidance in the various forms of discernment available to you.
