ANSWER: God had wrought in creation and then rested from His works when He had finished them, but man did not enter into it. Neither did Joshua nor David give God's people rest; so that the rest of God is still future, and believers will enter into it. We are to take care not to appear as though we come short of it. Now our portion is laboring as Christians; it will be resting when God's rest comes.
