"Let Us Ever Walk with Jesus"

About a month ago, one of the hymns on Worship Anew was "Let Us Ever Walk with Jesus."  I noticed that the line "Full of faith and hope and love" in the first verse exhibits polysyndeton (the repeated "and") and that the repetition here provides a sense of this abundance (being "full").

I also found an uncited Biblical reference.  The lines "Though today we sow no laughter, / We shall reap celestial joy" in the second verse draw from Psalm 126:5:  "Those who sow in tears shall reap with shouts of joy!"

(Here's a link to my post on the other Biblical sources.)
