Hebrews 4:1; Hebrews 4:6-8
Therefore, since the promise of entering his rest still stands, let us be careful that none of you be found to have fallen short of it.
It still remains that some will enter that rest, and those who formerly had the gospel preached to them did not go in, because of their disobedience.
Therefore God again set a certain day, calling it Today, when a long time later he spoke through David, as was said before: "Today, if you hear his voice, do not harden your hearts."
For if Joshua had given them rest, God would not have spoken later about another day.
