Hebrews 4:1, 3, 10-11

Therefore, while the promise of entering His rest still remains and is freely offered today, let us fear, in case any one of you may seem to come short of reaching it or think he has come too late.

For 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]. [Ps 95:11]

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].
