Most Religious Song in the Mormon Songbook

Name the most genuinely religious song in the songbook that the LDS church has approved for the Sunday spirituality of children.

For outsiders, the LDS church (often mis-identified as the Mormon church) has made a great effort over the past half-century to restrict decision-making power among adherents to the smallest possible number of men, residing in Salt Lake City, Utah, USA. All matters of LDS spiritual life are determined by Salt Lake City fiat, from what notions of god are â??trueâ?, to things as trivial as whether or not a person can blow a trumpet in an LDS chapel (that would be: no).
