3 In the name of Jesus Christ I ordain you to be a priest (or if he be a teacher, I ordain you to be a teacher) to preach repentance and remission of sins through Jesus Christ, by the endurance of faith on his name to the end. Amen.
As one who teaches youth who are 12-14, reading those verse encourages me to lift my sights and see the potential that my students have to be ministers of the Gospel. Ultimately, the calling as a Priest or Teacher that Moroni describes is similar to the calling of a missionary. If I can help those I teach see that, then I can encourage them to live now as if they are missionaries, because that is in fact exactly what they are.
