A capella music is the correct form of worship

I would like to start with rebutting my opponents claim that the bible condones musical worship. The Bible is split into the old and new testaments as you well know. The new testament is where we find the rules that regulate our ethics and morals. The old testament is a history of the Hebrew nation. You agree yourself that we do not use the laws that governed Israel 2000+ years ago. If you did, then you would be asking things like: 'Why are you not sacrificing the best lambs you have?' With the death of Jesus, the ceremonial law and Levitical Priesthood have ended and we are now commanded to sing with the instrument of the heart, that is, WITHOUT instruments[1]. The old testament has come to a close and we are no longer under the old law. We have a new one that governs humanity ever since the first century. Under this law, we are not given permission to sing with musical accompaniment. The fact of the matter is that: WE ARE NEVER TOLD TO DO IT in the new testament. And we can only use the New testament because the Old testament is now just a historical record for us, not a law. For, on the one hand, there is a setting aside of a former commandment because of its weakness and uselessness. (Hebrews 7:18) And so, in fact, the New testament does not permit Musical instruments. My argument is that since God does not condone it, it cannot be done. The Old law couldn't fit the expansion of God's attention to the rest of humanity after the Jewish nation ceased to be his chosen people. So the new covenant was made, for everyone else. Its that one which we are under. My opponent is pretty confident under the illusion that since Musical instruments are not found in the new testament, it is perfectly fine to do whatever we want. This is not true at all. Where the bible is silent, we must be silent too. Consider the Bible teaching about worship. John 4:23,24 - We must worship God in spirit and in truth. But God's word is truth (John 17:17), and all truth is revealed in the gospel (John 16:13). It follows that any practice is unacceptable if it is not included in the gospel. Matthew 15:9,13,14 - Worship is vain (worthless) when based on precepts of human origin. But every religious practice is based either on God's authority, or else on man's authority (Matthew 21:23-27). Since the Bible reveals everything that God ordained, then any practice which is not revealed in the gospel must be human in origin and therefore displeasing to God. [2] By adding extra to the commands which we are given, we explicitly ignore one of God's commands. For I testify unto every man that hears the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book... (Revelation 22:18) So we see that is unacceptable to add anything to worship practices that are not condoned. Doing so means CONDEMNATION! D: [1]The Westminster Confession of Faith states, Besides this law, commonly called moral, God was pleased to give to the people of Israel, as a church under age, ceremonial laws, containing several typical ordinances, partly of worship, prefiguring Christ, His graces, actions, sufferings, and benefits; (Heb. 9, Heb. 10:1, Gal. 4:1–3, Col. 2:17) and partly, holding forth divers instructions of moral duties. (1 Cor. 5:7, 2 Cor. 6:17, Jude 1:23) All which ceremonial laws are now abrogated, under the New Testament (Col. 2:14,16,17, Dan. 9:27, Eph. 2:15–16)" (19:2). [2]http://www.gospelway.com...
