There is nothing God delights in more than completely and totally entrusting ourselves to Him, and by holding up His end of the bargain that this trust, this faith is not in vain.
We begin a time of preparation to renew the New and Eternal Covenant (or perhaps, to enter into this Covenant for the first time). Covenant is the way God has chosen to renew us and, in fact, all of creation.
Leprosy wasn’t the problem. It’s a sign of a much deeper problem. And that problem still affects us today. Not only have we been given the cure to that problem, but we have also become the instrument of that cure for everyone else.
Jesus continues to performs “works of power” within us by the Spirit. This whole day is meant to be a day to revel in this, revel in being recreated, here and now. We will be sent out the other six days, and the Spirit will work through us to renew the world. But for one day, on this one day we rest. We allow the Lord to come and to perform his works of power within us.
