This Isaac Watts (I love Isaac Watts for the record) hymn is based on the second half of Psalm 72, which includes the words (in verse 17), “His name shall endure for ever: his name shall be continued as long as the sun: and men shall be blessed in him: all nations shall call him blessed.” If you’re interested in how the language of the sun traveling (running successive journeys) jives with modern science, then read about solar orbit HERE. The ‘Solar Orbit’ post has received very little traffic, but it is actually one of my favorite posts, and I refer to it fairly regularly in conversation as an example of how scientific opinion is always changing.
This version is not great. It is a song that is meant to be sung by congregations more than individuals, but it’s the best I could find that included the lyrics.
