Mark 2: 23-28
Jesus declares not that he has come to reform religion but that he is here to end religion and replace it with himself.
In religion, the purpose of obeying the law is to assure you that you are all right with God. As a result, when you come to the law, you are most concerned about details.
When Jesus says, “I am the Lord of the Sabbath,” Jesus means that he is the Sabbath. He is the source of the deep rest we need.
On the cross, Jesus said of the work underneath your work — the thing that makes you truly weary, this need to prove yourself because who you are and what you do are never good enough — that it is finished. If you rely on Jesus’ finished work, you can be satisfied with life.
You can take all the vacations in the world, but if you do not have the deep rest of the soul, resting in what Jesus did on the cross, you will not truly rest.
