I suppose you have heard the denominational attempt to justify the use of instrumental music. One of them goes like this: “The Bible neither forbids or commands the use of musical instruments in church, therefore it is acceptable to do if a church so desires it.”
Have you ever noticed how many evil things the bible never once forbid nor commanded? For instance, the bible never once forbid nor commanded gay marriage. Yet, most agree that such is an abomination. Why? Because the bible affirmatively said marriage was between one man and one woman (Gen 2:24). Secondly, homosexuality was condemned as an abomination (Rom 1). The bible never once forbid nor commanded many things, but does this mean that we can do them? Certainly not!
Peter commanded we are to speak the very words of God (1 Pet 4:11). Paul commanded we are not to go beyond that which was written (1 Cor 4:6). John wrote we are not add to or take from God’s Word (Rev 22:18,19). Denominations and some very liberal brethren refuse to adhere to God’s silence. When the new testament doesn’t validate their perversion, they run to the old testament. When that isn’t enough they run to lexicons and commentaries to change God’s intent.
In both the old and new testaments, God forbids anyone from altering his word (Deut 4:2 ff; 5:32;12:32; Prov 30:6). If the bible had to specifically forbid something in order for man to know not to do it, the world could not contain the books. Instrumental music epitomizes the silence of God. God commanded Christians to sing and make melody in the heart to the Lord (Eph 5:19). No, God didn’t have to condemn all forms of music in order to make it clear that A Capella was the only form of music which received his approbation. This verse excludes all other kinds of singing. It’s a mortal sin to add to or take from God’s Word. Once you understand this, A Capella makes perfect sense.. As Paul said subsequent to how we are to sing, “ And whatsoever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him (Col 3:17). There is no better proof than this!
