Jesus gave his life for us so that we can have him. Any matter you break bread over has been moved from an emotional matter to a covenant matter. You are making a claim that heaven cannot refuse. When people want to invoke supernatural forces of darkness against people, they go into some levels of covenanting.
There are certain demands that only a wife can make of her husband or only a man can make of his wife, because of the covenant between them. So, when we talk about the communion, it’s not just that we gather together to eat bread and drink wine; we are standing on a covenant ground and that’s the place and time to bring your requests. I can’t think of anything else that can give you a solid ground of faith to stand on stronger than the communion.
A wife doesn’t need any special faith to bear her husband’s name, she has every right given by the act of marriage to answer to her husband’s name. If you understand the covenant nature of our relationship with God, you will know that you don’t need any special faith to use the name of Jesus. The act of breaking bread is re-enacting the covenant before heaven again. We are the beneficiaries of this covenant as believers. God cannot look at us the same way he looks at every other human being.
