You are correct, there is no prohibition mentioned.
However, the bible gives many examples and patterns of how we are to worship and none include instruments.
Having said that, when the judgement day comes will the Lord say to a man "you have been a good servant but you played a guitar when you sung praises to my Father so you can not enter the Kingdom?" I will not pretend that I can speak for God, but as I see this issue of instrumental music in worship I'd rather not add to what has been revealed.
An example that I have heard used to illustrate the point of agruing from silence goes back to Noah and what was revealed to him for the construction of the ark.
Gen.6
[14] Make yourself an ark of gopher wood; make rooms in the ark, and cover it inside and out with pitch. [15] This is how you are to make it: the length of the ark three hundred cubits, its breadth fifty cubits, and its height thirty cubits. [16] Make a roof for the ark, and finish it to a cubit above; and set the door of the ark in its side; make it with lower, second, and third decks.
Very specific in his commandment to Noah. There is no specific prohibition to Noah against putting a flag pole to fly his family seal.
Now, the question is this:
Would Noah be disobeying God if he decided to add a flag pole?
do you realize how silly your arguments have become? This tells me that you have no support fro your position. NONE!
God said to Noah: "And this is the fashion which thou shalt make it of....
God gave Noah the basic outline and the absolute requirements. The rest was up to the discretion of Noah. I can't help but notice that God didn't tell him to build ramps or stairs between the decks, did he? Don't you think he put some in? Now would Noah have been in violation of God's Commandments if he had built some ramps? And what about furniture? Would Noah have been in violation of God's commandments if he put a bed in the boat? Of course not. I'm sure God knew that Noah would do whatever was within his discretion to get the job done. Did he use nails? Was he told to use nails? NO! Was he told to use dowels? NO! Was he told how to cut the wood? NO! Was he told to use 2x4's or 4x4's? NO! Was he told whether or not to dry the wood before he cut it into lumber? NO! And did he put a flag pole on it? Who cares?
There were a lot of basic things that were necessary to build the ark that God did not even discuss with Noah. He basically told him to build it according to his outline and the methodolgy was entirely up to Noah.
The same can be said of worship. God tells us to worship him. He gives us the basic outline and quite frankly that basic outline is set forth in the Psalms in the Old Testament and that method included using all sorts of musical instruments in worship and praise. He does not tell us that with the New Covenatnt that we are to abandon the methods of worship that were traditionally a part of his Chosen People.
Here's a question. Has God authorized you to discuss religious matters on a computer? I don't think you will find any such commandment in the New Testament. If you want to be consistent, you will use the new testmaent method and get out your quill and grab a piece of lambskin or papyrii before you respond to this post. And you will write it in either greek, hebrew or Aramaic.
