The first two lines of the second verse are "Elect from ev'ry nation, / Yet one o'er all the earth," sung to these phrases from the tune "Aurelia":
The phrase "o'er all the earth" is sung to all different pitches (B A G F#), musically giving a sense of that breadth.
The fifth (and last) verse ends with the lines "That we, like saints before us, / May see You face to face," sung to these phrases:
The two "face"s are both sung to the same pitch (D), so even musically, they're on the same level, eye-to-eye, as it were.
