We can mention only one point (which experience confirms), namely, that next to the Word of God, music deserves the highest praise. No greater commendation than this can be found — at least not by us. After all, the gift of language combined with the gift of song was only given to man to let him know that he should praise God with both word and music, namely, by proclaiming [the Word of God] through music.
Martin LutherDearest Jesus, holy child, make thee a bed, soft, undefiled, within my heart, that it may be a quiet chamber kept for thee.
Martin LutherRest in the Lord; wait patiently for Him. In Hebrew, "Be silent in God, and let Him mould thee." Keep still, and He will mould thee to the right shape.
Martin Luther
