Phrases like "I found Jesus" or "y'all need Jesus" have a lot of longevity because they describe a sentiment of experiencing salvation and reconciliation in terms that are understood by a large part of the population.
Instead of "Jesus" you could say "I found my purpose in life" or "I found love" and I think you'd be expressing nearly the same sentiment.
Probably not the root of what you're looking for, but when I was growing up in the 70s there was a national Christian campaign called the "I Found It* campaign. The church I grew up in participated and I Found It yard signs and buttons and billboards and radio ads and TV ads sprouted every where.
Of course the answer to *what did you find?" Was always Jesus, or eternal life or something like that.
