We all have a contribution to make to society and as members of the church some people are trained and set aside to enable others to minister in both their local community and their place of work. It may be as a priest, a deacon, or a lay person. God may be calling you to these or other ministries. The calling will be appropriate to your gifts and abilities and equally to do with God's purposes for creation.
We cannot do everything and there is a sense of liberation in realizing that. This enables us to do something, and to do it very well. It may be incomplete, but it is a beginning, a step along the way, an opportunity for God's grace to enter and do the rest.
from Prophets of a Future Not Our Own - Archbishop Oscar Arnulfo Romero
