I think part of some of the changes is that the Lord sees the adversary is targetting the youth at a younger age. He's trying to target the youth with pornography and other vices as early as 10 years old now in the public schools. I'm not exaggerating on the age of 10 by the way.
So it's natural that we would step up trying to help the youth gain testimonies at younger ages and help them know what light and the love of the Savior feels like at a younger age too. Just think...it's possible that maybe some of them will feel the love of the savior in the temple. Maybe some of us will feel that too and we hope for it. We hope to be like him, and follow him, and be with him.
I just hope the youth growing up and us as well will encourage and help each other enough that we can all endure to the end.
