“For we which haue beleeued do enter into rest, as hee said, As I haue sworne in my wrath, if they shall enter into my rest, although the works were finished from the foundation of the world.”
1611 King James Version (KJV)
4:3 For we only that have believed enter into the rest - The proposition is, There remains a rest for us. This is proved, #Heb 4:3 |- 11, thus: That psalm mentions a rest: yet it does not mean, God's rest from creating; for this was long before the time of Moses. Therefore in his time another rest was expected, of which they who then heard fell short Nor is it, The rest which Israel obtained through Joshua; for the Psalmist wrote after him. Therefore it is, The eternal rest in heaven. As he said - Clearly showing that there is a farther rest than that which followed the finishing of the creation. Though the works were finished - Before: whence it is plain, God did not speak of resting from them.
Heb 4:3 For we which have believed. Believers in Christ. Do enter into rest, as he said. Have the hope of the promised rest. To have the rest is conditioned upon a trusting faith. If they shall enter into my rest. Rather, "They shall not enter into my rest" (Revised Version). It is the same quotation that is found in Heb 3:11. The argument is that the Israelites were excluded from God's rest, and hence it follows that some others must enter in, since the rest has not been prepared in vain. Although the works were finished from the foundation of the world. Though God completed his work in six days and rested the seventh, a type of the rest to be given to his saints, yet keeping the Sabbath is not entering into that rest.
