To say a yes to God means answering a call, rather than initiating it. The process leading to that answer and later affirmation by the Church is called discernment. In some ways, vocation discernment is similar to career planning.Both involve recognizing talents and personality traits suited to work tasks. However, recognizing a vocation is so much more than deciding on a career. We choose our career. Our vocation is God’s choice of us.
Vocation means a call. It is God’s invitation, His call to each person to love and serve Him and His Church in a particular state or way of life. Each person's vocation flows from the grace of Baptism.
