New Is New Or It's Not New

A new commandment which is the same as the old.

What does it mean.

Firstly, get it in your head that it's a new commandment. 

It's a new one.

Not a rehash of the old.

Not a new way of keeping the old. 

It's new. 

New!

When you get that in your head, then you're ready to learn what it means that it's the same as the old.

It can only mean it fulfills the old.
