Matthew 5

In His Sermon on the Mount, the Savior taught -

"Ye are the light of the world. A city that is set on an hill cannot be hid.
15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."  (New Testament | Matthew 5:14 - 16)

Obviously, the Lord intended for us to have high standards and live in such a manner that would much higher than the world.

In a week and a half, we are holding a stake youth devotional based upon the youth standards established by the Church.  Our stake youth council have voiced that as a portion of this devotional involve a panel of youth and return missionaries that would answer questions by the youth.  As I read most of these questions, the questions seemed to follow why certain standards that vary from the world as well as where the line is for those standards as if they want to see how close they can come to the "world".  I note a portion of the lyrics of a popular hymn -

High on the mountain top,
  A banner is unfurled.
  Ye nations now look up;
It waves to all the world."
In Deseret's sweet, peaceful land-
On Zion's mount behold it stand!

For God remembers still
  His promise made of old
  That He on Zion's hill
  Truth's standard would unfold!
Her light should there attract the gaze
Of all the world in latter days.
I note that the nations will have to "look up" to "truth's standard".  In modern day, the Lord revealed -

"...even so I have sent mine everlasting covenant into the world, to be a light to the world, and to be a standard for my people, and for the Gentiles to seek to it, and to be a messenger before my face to prepare the way before me."  (Doctrine and Covenants | Section 45:9)

This would be the answer to almost all their questions.
