Father Michael Cupp pointed out to us that promises made to Israel, now fulfilled in Jesus, with the end result still future, is very much into, for and about this world (Joshua 5:9-12). Even as it brings another world not only into the picture, but somehow into the reality of life. That was realized then with the promise of land, actual land on earth, fulfilled during Joshua’s time beginning with Moses, the initial promise made to Abraham. And the manna rained down on them daily, except on the Sabbath, God’s provision for them on their journey to the Promised Land. Literal food for them on earth from heaven. And how we now partake of the body and blood of our Lord through the Sacrament of the Eucharist. Not in the sense described by the Roman Catholics (nor the Lutherans), but in some mysterious sense. The point being that the heavenly from God in Jesus by the Spirit is very much for earth, for our existence in this life, as well as in the life to come when heaven and earth become one in Jesus.
We are victims of a Modernist mindset which demotes heaven into some upper story, surreal existence, which is quite okay for those who want to participate in that, but has nothing to do with the lower story where we actually live: reality. But just as Jesus came down from heaven as the Bread of Life to give life to the world, so we in Jesus receive spiritual sustenance to live that same life in Jesus and Jesus in us even here and now.
