The Hebrew translated as rest…
katapausis… 1 a putting to rest. 1A calming of the winds. 2 a resting place. 2A metaph. the heavenly blessedness in which God dwells, and of which he has promised to make persevering believers in Christ partakers after the toils and trials of life on earth are ended.
–Enhanced Strong’s Lexicon
In a rest-less world… who doesn’t want to enter His promise of rest…
Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem to have failed to reach it.
Hebrews 4:1 ESV
