"Onward Christian Soldiers" is a Christian hymn written by Sabine Baring-Gould (1834-1924), who was an Anglican priest. A proper interpretation of this song shows it's about spiritual battle: If the song is about spiritual battle, why are there knights on horses? Because towards the end of the video I quote from the book of Revelation 19:14-15, which mentions the armies of heaven riding on horses.
I used deepai.org (artificial intelligence) for the image but I made some alterations by hand in Affinity Photo 2. I used suno.com (artificial intelligence) for the music. I used lalal.ai (artificial intelligence) to separate the music into 2 tracks so I could (human work) mix and master the song in Reaper. The video was edited in Filmora 13 (human work). While AI is doing a lot of the work, I assure you I also do a lot of work. I briefly describe what is involved in making a song-video here:
If you're into Christian metal this is probably the video for you. If not, you still might enjoy it. Remember, God loves everyone, and so should we. Be nice to each other, even if you disagree. Have a great day.
