Hebrews 4:3-10

3For we who believe [that is, we who personally trust and confidently rely on God] enter that rest [so we have His inner peace now because we are confident in our salvation, and assured of His power], just as He has said, “As I swore [an oath] in My wrath, They shall not enter My rest,” [this He said] although His works were completed from the foundation of the world [waiting for all who would believe].

4For somewhere [in Scripture] He has said this about the seventh day: “And God rested on the seventh day from all His works”;

5and again in this, “They shall not enter My rest.”

6Therefore, since the promise remains for some to enter His rest, and those who formerly had the good news preached to them failed to [grasp it and did not] enter because of [their unbelief evidenced by] disobedience,

7He again sets a definite day, [a new] “Today,” [providing another opportunity to enter that rest by] saying through David after so long a time, just as has been said before [in the words already quoted], “Today if you hear His voice, Do not harden your hearts.”

8[This mention of a rest was not a reference to their entering into Canaan.] For if Joshua had given them rest, God would not speak about another day [of opportunity] after that.

9So there remains a [full and complete] Sabbath rest for the people of God.

10For the one who has once entered His rest has also rested from [the weariness and pain of] his [human] labors, just as God rested from [those labors uniquely] His own.
