Let's look at the way ancient Hebrews made their covenants. Let's make spiritual application to each, keeping in mind-we're really talking about what it means to be a Christian in our day. A man's robe was symbolic of all his material possessions. Therefore, by giving his robe, he was pledging everything he had to his covenant brother. Now it's our turn.
Salvation has to do with ownership.
We pledge our possessions, our hearts, our all, to our covenant brother. We now own nothing. That's not a symbolic act. It's a fact. I now give to you.
