Well, it isn’t the dangers themselves that are the focal point. Rather, it is the fact that God’s wise hand was with them at all times, guiding them even in the midst of dangers. When the Israelites were hungry, God fed them manna from heaven. When they were thirsty, God gave them water from the rock. This is a portrait of a loving God, a parent who really cares about his children.
Some of us had the blessing of being raised in a large family without riches (in the sense of material possessions). But we were greatly blessed because of the spiritual riches all around us. Good Catholic parents who made the Holy Eucharist the centre of life for our family. Good Catholic education from our parents, and maybe a parish school or a state school with religious educators on a weekly basis. Good food on the table, although the portions were sometimes very modest. Good social justice lessons, since somehow there was always something to share with other families with similar needs, such as hand-me-down clothing. God’s wise hand was clearly seen and gratefully acknowledged by us every single day.
This is what the Israelites were experiencing, to learn to trust in God and his wisdom. The disciples of Jesus discovered that as they also, came to understand and believe that the Holy Eucharist was indeed the very flesh and blood of Jesus, in sacramental form. Jesus had gone, but he was still here! God truly provides for his children, even into eternal life.
The Eucharist is our pledge of the glory to come. Like the Israelites of the Old Covenant remembering their desert journey, we remember the promise of the New and Everlasting Covenant, first celebrated at the Last Supper. We are fed and strengthened by this Eucharist to live the life of Christ. This is the nourishment for our daily desert journey, the medicine for our life in Christ.
