Rock music is discordant music it is out of the flow of nature . God said " Let there be Light ! " through sound is how the universe was created . Nature itself has a built in rhythm which is 4/4 , 3/4 , 6/8 . 12/8 and so on . The human heart beats follow 3/4 rhythm so imagine what it does to people's hearts when they listen to music that is out of this sync with this rhythm ? The music might feel good cause it pushes the energy from the heart down to the groin area , but does the opposite to enhance people's spirituality . They have done scientific experiments with plants and they have been shown to die off listening to this kind of music . Classical music is in tune with nature so it has a uplifting quality which been proven to help plants grow the opposite of discordant music. Musicians will say I don't want to play that kind of music its boring the if it " feels good do it " mentality . They want to play music that has a syncopated beat that breaks the rhythm of life.Where do you think this music comes from ? Who wants to rebel against the nature of God and break down life ? . And for people to play rock music in churches ? I am sure this is the kind of music that the Jews where playing when they danced around the golden calf . People in todays churches are creating these spectacles with this kind of music . Instead of a place where people have a quiet time and reflect on God if the "Kingdom of God is within you " as Jesus Christ told us how can you hear him if people are rocking out ? If people knew better they could do better .
