I've had an impressively easy time finding particular messages as long as I had a decent idea of what servers it might have been in and at least one of the following:
- Who said it
- To whom it was said
- At least a word that was likely said
Which has been way better than most other things I've bothered to search through like Reddit, Beehaw, or Mastodon (especially when it was limited entirely to hashtags). Lord help me if I want to find a particular post or comment on TikTok or Youtube.
You heard it that way because that's because that's the end of 1 Corinthians 13:11:
C.S. Lewis is playing off of a Bible quote and that became its own thing.
