Hebrews 4:3-13

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 somewhere [in Scripture] He has said this about the seventh day: “AND GOD RESTED ON THE SEVENTH DAY FROM ALL HIS WORKS”; [Gen 2:2] and again in this, “THEY SHALL NOT ENTER MY REST.” [Ps 95:11] Therefore, 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, He 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.” [Ps 95:7, 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. 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]. For the word of God is living and active and full of power [making it operative, energizing, and effective]. It is sharper than any two-edged sword, penetrating as far as the division of the soul and spirit [the completeness of a person], and of both joints and marrow [the deepest parts of our nature], exposing and judging the very thoughts and intentions of the heart. And not a creature exists that is concealed from His sight, but all things are open and exposed, and revealed to the eyes of Him with whom we have to give account.
