Biblical citations in the hymnal: Philippians 1:9, Leviticus 19:34, 1 John 4:12
Philippians 1:9: "And it is my prayer that your love may abound more and more, with knowledge and all discernment"
Leviticus 19:34: "'You shall treat the stranger who sojourns with you as the native among you, and you shall love him as yourself, for you were strangers in the land of Egypt: I am the LORD your God.'"
1 John 4:12: "No one has ever seen God; if we love one another, God abides in us and his love is perfected in us."

All of the cited passages seem to be combined in the lines "Lord of all nations, grant me grace / To love all people, ev'ry race" in the first verse and the line "Let Christian love bind warm and true" at the end of the second. The rest of the hymn text expands upon these.

There's a significant line break in the lines "Break down the wall that would divide / Thy children, Lord, on ev'ry side" in the second verse. It interrupts the meaning (separating the verb from its direct object), and this draws attention to that division.
There's a slant rhyme between "erred" and "word" in the lines "Forgive me, Lord, where I have erred / By loveless act and thoughtless word" in the third verse, and to some degree, this emphasizes both the meaning of "erred" and the "thoughtless" nature of that "word."
