The sacraments are seven great gifts that God has given to us. Although we cannot see it, each time a person receives a sacrament, special grace comes through God to that person. These graces help us to reach heaven.
Baptism is the first sacrament a person receives, and is the only one that we have to have to go to heaven.
When Adam and Eve sinned in the Garden of Eden, by eating the forbidden fruit, God punished them. He put the mark of original sin on their soul. When we are born, we too have this mark. The Blessed Virgin Mary is the only person who has ever gone without it. With the mark of original sin on their soul, no one can go to heaven. That is why we are baptized as soon as possible after we are born. Baptism washes away that mark and makes us children of God with the right to go to heaven. A priest baptizes by pouring water on the forehead of the person to be baptized and saying the words, “I baptize you in the name of the Father, and of the Son, and of the Holy Ghost.”
