On the issue of #15's precise wording, Google shows 363 results for "Hearts unfold like flowers before Thee clearly as the sun above" vs. 191,000 hits for "Hearts unfold like flowers before Thee opening to the sun above". And I second Ron Davies' question about its "Christmas" connection. Of course in a supremely broad sense virtually any Christian hymn could be called a Christmas carol, but usually the label is only applied to those songs topically connected with Christmas (including Advent and Epiphany) and/or with Winter.
