* the true sabbath is not in the law of Moses:
"For if Joshua had given them rest, then He would not afterward have spoken of another day.
There remains therefore a rest for the people of God.
For he who has entered His rest has himself also ceased from his works as God did from His.
Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience."
Hebrews 4:8-11
* Christ is the true sabbath:
"Come to Me, all you who labor and are heavy laden, and I will give you rest.
Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.
For My yoke is easy and My burden is light."
Matthew 11:28-30
* we should be in Christ everyday, not only once a week...
"Then He said to them all, If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me."
Luke 9:23
"Then Jesus said to those Jews who believed him: If you continue in my word, you shall be my disciples indeed."
John 8:31
