We live by the promise. This is why I’ve taken to saying right before we eat and drink, something like, “Believe and live.” Not that the physical bread and wine we consume gives us spiritual life. But by faith we claim the promise, we do what our Lord Jesus told us to do, and He does really bless us in it. Life is communicated from the Jerusalem above, our mother. We are in the womb, needing nourishment. Consider your baptism the setting up of that connection, this table the food itself. Without faith, there’s a blockage and we aren’t fed. But with faith, our claiming the promise week by week at this table and hearing the Word gives us strength and growth.
