I found this to be an interesting thought and a practical way to bring home the idea of Piper's Christian Hedonism. All of creation has a sacramental aspect to it and has strengthening grace in it to those who approach in faith and awe. The grace of God can be found all around us in creation. Or as Doug Wilson puts it:
"If understood, this results in mediated grace for everyone who is responding to God in true faith. God does grants immediate grace in various ways, true. When He converts a soul, when He visits someone with direct blessing, when He receives our worship, the grace can be immediate. But this immediate grace is supposed to be a radiant grace, spreading out through everything else, affecting everything else, causing everything else to become a mirror that reflects the glory of God.
If we don't get this, we will start to think of ourselves as deep sea divers, who have a grace hose running from our helmet up to Heaven, and the only way we can get grace is through that hose. But God is the one in whom we live and move and have our being (Acts 17:28). We are living in the presence of God where it is actually possible to offer thanks for all things (Eph. 5:20)."
