Isaiah 55 KJVhttp://bible.cc/isaiah/55-1.htm
"Ho, every one that thirsteth, come ye to the waters, and he that hath no money; come ye, buy, and eat; yea, come, buy wine and milk without money and without price."
Sometimes people tell lies but their training does not let them see what is happening.
Isaiah 55 actually commands us not to give our food money for that which is not food.
The Word is free and like the water cycle: it falls free of charge and does its work. Then it returns to God who gave it.
In Isaiah 58 the true rest (PAUO) tells us not to seek our own pleasure or SPEAK our own words.
Jesus exampled that.
Paul in Romans told us not to seek our own pleasure: the word in Greek and Latin identifies all of the performing arts which do nothing but create the "mental excitement" which REPLACES and nullifies the direct command to:
Use one mind and one mouth to speak "that which is written for our learning" which is defined by Paul as Scripture.
That was the historical practice fo centuries.
Unfortunately men wanting to be evangelists are trained to be preachers which means sermonizing tidbits of Scripture to validate their own experiences or opinion.
Both poetry and music were called lying: 2 or 3 removes from the truth.
Aristotle: Melody Deceives: "Poets also make use of this in inventing words, as a melody "without strings" or "without the lyre"; for they employ epithets from negations, a course which is approved in proportional metaphors..
The form of diction should be neither metrical nor without rhythm.
If it is metrical, it lacks persuasiveness, for it appears artificial, and at the same time it distracts the hearer's attention, since it sets him on the watch for the recurrence of such and such a cadence..
According to Philo, the gods of the pagans exploit this weakness of men. For the sake of a better effect, and with the intention of more easily cheating their devotes, that they have set their lies to melodies, rhythms and meters.."
Every preacher should examine themselves whether they are sincere and whether they are obeying the direct command which cannot be misunderstood: to PREACH the Word by READING it and making sure that people learn it. That's what Paul commanded Timothy to do.
