The point about the passage quoted here from Psalm 95 and the historic events it describes in Numbers is that this process of provocation of God, of hardening of the heart, and of God’s patience being exhausted, has already been lived out in the case of Old Testament Israel. In their case what God offered was the typical blessing of rest in the land of Canaan and they were denied that rest because of their unbelief. But the warning is to us, the New Testament people of God, that if we harden our hearts in unbelief, we too may be denied his blessing and fall short of the salvation that is held out to us in the promise. We may have stood for a time among the professing people of God, but we may prove ourselves to lack the faith which identifies us as true children of God.
