“For the Word of God is the sanctuary above all sanctuaries, yea, the only one which we Christians know and have. For though we had the bones of all the saints or all holy and consecrated garments upon a heap, still that would help us nothing; for all that is a dead thing which can sanctify nobody.
But God’s Word is the treasure which sanctifies everything, and by which even all the saints themselves were sanctified. At whatever hour then, God’s Word is taught, preached, heard, read or meditated upon, there the person, day, and work are sanctified thereby, not because of the external work, but because of the Word which makes saints of us all. Therefore I constantly say that all our life and work must be ordered according to God’s Word, if it is to be God-pleasing or holy.”

Martin Luther, Large Catechism
