Illinois State University is hosting the event, expecting around 1,300 people to fill convention rooms in the Bone Student Center.
This is the second of three nation wide gatherings with the first convention in Nevada and the third to be in Georgia.
Youth will attend different lectures on the books of the Bible and Christian living, worship four times a day, and have a divine service twice during the week.
Rachel Groll, a conference participant says, "It's a lot of fun. It's not all about just your faith, but you come and you learn more and then just the friends that you make too. It's a really good experience."
Pastor Chris Hull explained that the conference gives youth a chance to figure out who they are in this world and what it means to be Lutheran.
