In the Baptist church of my childhood, we often sang the hymn "He Paid a Debt He Did Not Owe":
He paid a debt he did not owe
I owed a debt I could not pay
I needed someone to wash my sins away
And now I sing a brand new song
Amazing Grace all day long
Christ Jesus paid a debt that I could never pay
At the time, I was unaware that I was bearing witness to a truth about the natural law: My conscience told me that things were not as they ought to be - that I "owed a debt I could not pay" - and ultimately pointed me to Jesus Christ.
