Reclaiming the Name "Saint"
Scripture calls us holy while we still live on earth - if we believe. ... You are holy because you have God's Word, because heaven is yours, because you are truly pious and made holy by Christ. This must be your confession if you would be a Christian. For it would be the greatest disgrace and blasphemy of the name of Christ if we did not concede to Christ's blood the glory that it washes away our sins, or if we did not believe that this blood sanctifies us.
