New vs. Old
Some time ago I changed my gas supplier. New company, new contract, new price, new direct debit, new statements, new helpline number etc.
But, same underlying trust, same underlying integrity, same underlying governing laws, (i.e. same principles of conduct in supply and payment), same commodity supplied.
The current arrangement is new, and yet old. The old contract is obsolete. The new is in place. But, both were founded on lasting principles which are neither new nor obsolete.
So, how 'new' is the New Covenant?
