I have already countered all of these comments but I will do it again ...... Instruments in psalms are under old law ..... Instruments in revelations is symbolic like the four horsemen..... No we aren't given permission to use microphones with a specific scripture but the bible already speaks on how we are to praise God and if you can't find a New Testament example then you are adding and adding is sin..... And God did not leave us to our own "intelligence" God says it is not within man to direct his own steps! ......... And finally the idea that God will be pleased with whatever worship we give him is a lie , Uzah had good intentions but disobeyed and died ,, Aaron's sons gave unauthorized fire and God consumed them in it.... How more clearly do you need it spelled out? If God doesn't authorize it and he has spoken on it then it is sin!
