Sabbath is in Christ and Christ is in the Sabbath

"God’s rest is in the seventh day; and God’s rest is in Christ. 

It is impossible for God’s rest to be in antagonistic places; for as with God “there is no variableness neither shadow of turning,” (James 1:17) God’s rest is the same wherever it may be. 

Therefore, God’s rest being ever the same, 

God’s rest in the seventh day, 

and God’s rest in Christ, 

is precisely the same rest. 

And this, being impossible to be in antagonism, is in perfect unity, and therefore demonstrates that the Sabbath is in Christ and Christ is in the Sabbath."
