Hebrews 4:1-4 AMP
Therefore, while the promise of entering His rest 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.
[2] For indeed we have had the good news [of salvation] preached to us, just as the Israelites also [when the good news of the promised land came to them]; but the message they heard did not benefit them, because it was not united with faith [in God] by those who heard.
[3] 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].
[4] For somewhere [in Scripture] He has said this about the seventh day: “AND GOD RESTED ON THE SEVENTH DAY FROM ALL HIS WORKS”.

There is a rest that can only be enjoyed in God both physically and spiritually that will eventually culminate in the Sabbath rest of eternity.
God wants us to rest, not just the physical rest that is the state of quiet or repose, the cessation from motion or labor and rest from mental exertion of the body or mind but He also wants a spiritual for us even in this life.
God’s heavenly rest offered to the saints of old, continues today, and like some of them, we either refuse or fail to reach this rest. Jesus invites all who are burdened with sin and religious labor to come for rest.
He invites sinners, wearied in the ways of iniquity to come receive speedy relief.
Believers, tempted, and oppressed by the carnal mind, may come to Christ, and allow his blood, to cleanse them from all unrighteousness, and, purified them from all sin.
The rest offered here will release the believer from the yoke of routine religion, making them humble and meek like Himself, while granting them rest and peace.
God offers rest to the weary, tired, oppressed, and hopeless. Wherever you are right now that has become a burden and creates the spirit of fatigue can be refreshed in the Lord, He did not intend for us to care for ourselves hence His invitation in Psalm 55:22 and 1 Peter 5:7 to cast our burdens, anxiety, fears, and whatnots on Him, so we can pick up his rest.
We are his own, the sheep of his pastures that he feeds and directs with his powerful hand protecting us.
But we must hear his voice, “Today,” rightly used, you have no time to lose; tomorrow may be too late to enter the rest of God-salvation.
If we neglect and ignore His call and harden our hearts and ears to the sound of His voice; as the Israelites did and wandered in the wilderness for forty years, we too will face the consequences of not responding to the invitation for rest.
Forty years is a long time in one’s life to wander around without a firm plan and rest. Unbelief, doubt, and disobedience can keep us in a wilderness of our making, either physically stagnant or spiritually and financially crippled which will make it critical to seek and enter God’s rest.
Unfortunately, just as it was for the Israelites who disobeyed God, by failing to completely trust His promises, we can fail to enter the rest that is eternal life, as they failed to enter the Promised Land.
God’s rest is salvation!
The promise of rest refers to believers, especially as those to whom the promise was made failed to enter it. Their failure was not because the rest was unprepared, because it existed since the day that God finished His work of creation. This is the rest referenced in Genesis 2:2, God rest. God’s rest is true, and it is His purpose that anyone who trusts and obeys Him shall enter that rest.
A foretaste of the rest Is given in the inward rest that the believer’s soul has in Christ, a rest which, when once obtained, is never lost according to Revelation 3:12.
Do you desire God’s rest? Do not harden your heart, it’s not too late to enter God’s rest.
Shalom
