Hebrews 4:1, 11

Therefore, while the promise of entering His rest still 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.

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].
