"If Thou But Trust in God to Guide Thee"

A couple months ago, one of the hymns in church was "If Thou But Trust in God to Guide Thee" (sung to the tune "Wer nur den lieben Gott"), and I noticed a small connection between the music and the text.  A pair of lines in the sixth verse are "'Tis easy for our God, we know, / To raise thee up, though low thou liest."  The second of these two lines is sung to this musical phrase:

There's an ascent for "To raise thee up," and a descent to describe "though low thou liest."

I also noticed that there's an accidental (an F# in G minor) for the second syllable of "evil" and for "it" (whose antecedent is "each dark moment").  However, these errant notes don't represent sin and its results in every instance.  This same accidental (in other musical phrases) also falls on the first syllable of "gladness" and on "rock" in "the rock that naught can move" (which represents "God's unchanging love").  Clearly, the implications of this accidental must be lookt at on a case-by-case basis.  Many of these little things I notice in hymns seem coincidental, but this especially so.
