Hebrews 4:8-11

[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. So there remains a [full and complete] Sabbath rest for the people of God. For 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. [Gen 2:2] Let us therefore make every effort to enter that rest [of God, to know and experience it for ourselves], so that no one will fall by following the same example of disobedience [as those who died in the wilderness].
