This meal signifies, in part, that God has an ongoing, future plan for you, and for every Christian. He does not want us to leave focused on the past, but on the future. Few things in life are as wonderful as to realize that God always has a future for us. As we leave, we are to face outward, and go to serve. The Church I grew up in, had a motto on the front of its bulletin.
Communion is similar.
We enter to worship, to be fed, to be strengthened, but then we leave to serve. We bring tokens, but we leave as tokens . . . Secondly, we are tokens of God's kindness. It is specifically his kindness that is noted here. First, one must know God's kindness.
