Hi Fredandmary,
The old Covenant was about 'the letter of the law'
And t he New Covenant is about "the spirit of the law".
While The old Covenant is no longer in affect:
'the letter of the law' and "the spirit of the law"
both still are. Though some Gematria might be found,
this thread is primarily about the law and how it applies in everyday life.

God bless
