Hebrews 11:32-40 (ESV)
And what more shall I say? For time would fail me to tell of Gideon, Barak, Samson, Jephthah, of David and Samuel and the prophets—  who through faith conquered kingdoms, enforced justice, obtained promises, stopped the mouths of lions,  quenched the power of fire, escaped the edge of the sword, were made strong out of weakness, became mighty in war, put foreign armies to flight.  Women received back their dead by resurrection. Some were tortured, refusing to accept release, so that they might rise again to a better life.  Others suffered mocking and flogging, and even chains and imprisonment.  They were stoned, they were sawn in two, they were killed with the sword. They went about in skins of sheep and goats, destitute, afflicted, mistreated—  of whom the world was not worthy— wandering about in deserts and mountains, and in dens and caves of the earth.
 And all these, though commended through their faith, did not receive what was promised,  since God had provided something better for us, that apart from us they should not be made perfect.
Apart from us they should not be made perfect. The story of Israel does not end with Malachi. It continues to the end. It is our story, and it is not completed, not made perfect without us. So just as we are commended, made righteous through faith apart from the works of the law, so were they. Remarkable the New Testament actually changed very little when it completed the Old Testament. Salvation has always been through faith.
