My son is really reaching his potential more and more in the mission field as evidenced by some of his emails to his mom. I quote just as few sentences from his last one to me: " I do feel a certain spirit when I use Spanish, it has a certain simplicity that is parallel to the plain and clear doctrines of the gospel. But I would recommend studying more the general conference talks, they will strengthen your testimony. They are the equivilent of modern scripture, and they are packed with the Espiritu Santo, or Holy ghost in Spanish."
The Lord is truly teaching and helping my son reach his true potential in His kingdom.
