"One does not ordinarily associate law books with songbooks, mandates with music. But Here's a man to whom the law of the Lord is no burdensome thing, a pattern of hard lines. Here's a radiant believer to whom law is liberty and service like unto a happy song.
One may be good in such a bad way. Some of us have punctiliously kept the statutes but have failed to sing the songs. We have whiteness but not light. The Christian life does have it's stern, unyielding requirements; but every law has a song written on the back and between the requirements runs the refrain. Duty turns to delight and mandates become melodies.
There must be a law if there is to be liberty. Try to play a piano and you will run into laws as fixed as the decrees of the Medes and the Persians. But through those statues you reach the songs, drudgery leads to delight. The law of Christ brings the liberty of Christ. Keel His statues, and they become songs. The other side of commandment is conquest. What seems restraint to the outsider means release to you.
'Ye shall know the truth'-- there are the statutes. 'The truth shall make you free' -- there is a song. But to know the truth is to know Him, otherwise it is legalism. If the Son shall make you free, ye shall be free indeed. His law book becomes a song book." ~Vance Havner
