Luther's prayer to receive the Word

Eternal God and Father of our Lord Jesus Christ, grant us Your Holy Spirit who writes the preached word into our hearts so that we may receive and believe it, and be gladdened and comforted by it in eternity. Glorify Your Word in our hearts. Make it so bright and warm that we may find pleasure in it, and through Your inspiration think what is right. By Your power fulfill the Word, for the sake of Jesus Christ, Your Son, our Lord. Amen.
