Rest is physical. Rest is emotional. Rest is mental and spiritual. It is the tangible expression of God’s presence: Rest.
In Exodus 13:14 God’s promise to Moses was, My presence shall go with you, and I will give you rest.
We are not a people looking for the presence of God; we already have it. He is inside us. You can’t get any more Presence than that: Inside you. Anything that happens externally is a fabulous bonus, but you don’t actually need it. Who doesn’t want the physical, tangible touch of God on their life? Here is the thing: If you practice rest, you will feel the touch of God so much more.
