The vocation of God that is addressed to us at Easter time is what is said in Saint Mark: "... go into the world, preach the Gospel to every creature...". God's vocation is important to be a priest or a religious or to be a lay person in consecration, or to get married.
A good example is Brother Joseph Ralaivao, who died at the age of 91. He worked in many places, when he decided to dedicate himself to becoming a priest. He was a teacher of architecture and crafts. He chose to become a brother so that he could work more to help young people, lay people and priests and religious in formation. There are two types of lay people: "religious" lay people and those who are married. There are two types of priests: religious who live in a particular way, and there are also diocesan priests who take care of the parishes.
