Brothers, let me take an example from everyday life.  Just as no one can set aside or add to a human covenant that has been duly established, so it is in  this case (Galatians 3:15).

Some years ago, my family was involved in a legal situation.  I won’t give any details, lest I become involved in another legal situation.

If you get my drift.  

Suffice to say that all parties met with attorneys and mediator people, and left the room with a common understanding and a signed agreement, 

which lasted for a day.

Then, one of the parties called to say that they had not understood the intent and details of the agreement, even though they signed a legal document stating that they understood the intent and details of the agreement.

Back to square one.

So, not to disagree with Paul, but I’m figuring contracts were a bit more iron-cladical in his day.  In any case, the point stands: God made a promise, and that promise is not going anywhere.  Our covenant is not with fickle man, but with faithful God.  And he’s not about to call you back and say he didn’t understand what he was signing.

Happy Friday, Beloved.
