Therefore, while the promise remains of entering His rest, let us fear so that none of you should miss it.
Hebrews 4:1 In-Context
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.
For we also have had the good news proclaimed to us, just as they did; but the message they heard was of no value to them, because they did not share the faith of those who obeyed.
Now we who have believed enter that rest, just as God has said, “So I declared on oath in my anger, ‘They shall never enter my rest.’ ”And yet his works have been finished since the creation of the world.
For somewhere he has spoken about the seventh day in these words: “On the seventh day God rested from all his works.”
And again in the passage above he says, “They shall never enter my rest.”
