I transcribed "I Am Trusting Thee, Lord Jesus" last month and found a few features to write about. Every verse begins with "I am trusting Thee...." This is a rhetorical device called anaphora, and in its use here, it illustrates the surety of that trust.
I also found a couple connections between the text and the music, specifically the last two phrases:
The tune is "Stephanos," a transliteration of στέφανος, the Greek word for crown.
The fourth verse ends with the lines "Ev'ry day and hour supplying / All my need." "Ev'ry" is sung with a melisma (C D E), musically giving a sense of frequency. The last (sixth) verse ends with the lines "I am trusting Thee forever / And for all." "Forever" is sung with a melisma (G A Bb A), musically giving a sense of duration, and "all" is sung to a whole note for a sense of entirety.
