Rest can lead to joy because
it creates a new perspective in us. When we choose to rest it can remind us that we do not have to be compulsively responsible for the world and everything in it. Rest can remind us that God is in charge, if we choose to do so.
it leads to a renewed relationship with God.
it restores us. It renews and re-energizes us because we can see life with new gratitude and awe.
it frees us to be what we are. We can choose to balance our working, giving and weeping with playing, receiving and laughing.
Isaiah 56:6b-7a
All who keep the Sabbath without desecrating it and who hold fast to my covenant -- these I will bring to my holy mountain and give them joy in my house of prayer.
