For this good news-- that God has prepared this rest-- has been announced to us just as it was to them. But it did them no good because they didn't share the faith of those who listened to God.
For only we who believe can enter his rest. As for the others, God said, "In my anger I took an oath: 'They will never enter my place of rest,' " even though this rest has been ready since he made the world.
So God set another time for entering his rest, and that time is today. God announced this through David much later in the words already quoted: "Today when you hear his voice, don't harden your hearts."
For the word of God is alive and powerful. It is sharper than the sharpest two-edged sword, cutting between soul and spirit, between joint and marrow. It exposes our innermost thoughts and desires.
