Accordingly, I swore in My wrath and indignation, They shall not enter into My rest. [Psa 95:7-11]
[Therefore beware] brethren, take care, lest there be in any one of you a wicked, unbelieving heart [which refuses to cleave to, trust in, and rely on Him], leading you to turn away and desert or stand aloof from the living God.
But instead warn (admonish, urge, and encourage) one another every day, as long as it is called Today, that none of you may be hardened [into settled rebellion] by the deceitfulness of sin [by the fraudulence, the stratagem, the trickery which the delusive glamor of his sin may play on him].
For we have become fellows with Christ (the Messiah) and share in all He has for us, if only we hold our first newborn confidence and original assured expectation [in virtue of which we are believers] firm and unshaken to the end.
Then while it is [still] called Today, if you would hear His voice and when you hear it, do not harden your hearts as in the rebellion [in the desert, when the people provoked and irritated and embittered the Almighty against them]. [Psa 95:7-8]
For who were they who heard and yet were rebellious and provoked [Him]? Was it not all those who came out of Egypt led by Moses?
And with whom was He irritated and provoked and grieved for forty years? Was it not with those who sinned, whose dismembered bodies were strewn and left in the desert?
And to whom did He swear that they should not enter His rest, but to those who disobeyed [who had not listened to His word and who refused to be compliant or be persuaded]?
So we see that they were not able to enter [into His rest], because of their unwillingness to adhere to and trust in and rely on the Almighty [unbelief had shut them out]. [Num 14:1-35]
