A Spiritual Sabbath
If you read the entire fourth chapter of the book of Hebrews, you will find it speaking about a Sabbath rest that is available to God's people. Under the Old Covenant, the Sabbath was observed as a day of rest. Under the New Covenant, this Sabbath rest spoken of is a spiritual place of rest. It is the privilege of every believer; you can enter the rest of God.
The only way to enter that rest is through believing. You will forfeit it through unbelief and disobedience. Unbelief will keep you in the wilderness, but Jesus has provided a permanent place of rest that can be inhabited exclusively through living by faith.
