God judges the thoughts and purposes of the heart.

Heb 4:12 For the word of God is living and active, sharper than any double-edged sword, piercing until it divides soul and spirit, joints and marrow, as it judges the thoughts and purposes of the heart.
Heb 13:9 Stop being carried away by all kinds of unusual teachings, for it is good that the heart be strengthened by grace, not by food laws that have never helped those who follow them.

A rest to the people of God

Heb 4:9 There remaineth therefore a rest to the people of God.
KJV

1)Heb 4:9 Queda, por tanto, un reposo sagrado para el pueblo de Dios. NBLH 2)Heb 4:9 Il y a donc un repos de sabbat réservé au peuple de Dieu. FLS 3)Heb 4:9 Er blijft dan een rust over voor het volk Gods. DSV

So we see that they were not allowed to enter and have God’s rest, because they did not believe.
And we still have the promise that God gave those people. That promise is that we can enter his place of rest. So we should be very careful that none of you fails to get that promise.
Yes, the good news about it was told to us just as it was to them. But the message they heard did not help them. They heard it but did not accept it with faith.
This shows that the seventh-day rest for God’s people is still to come.
So let us try as hard as we can to enter God’s place of rest. We must try hard so that none of us will be lost by following the example of those who refused to obey God.
ERV
