No I am not Amish, yes I have a cell phone, TV, Car and electricity in my home, yes I have flown on airplanes (I worked on them for over 30 years). when the apostles were told to "go" (Matt 28:19) did the Lord say how? no, a plane, train or automobile are "expedient", it does not change the command to "go".
When Jesus sat on the mount, he used the mount because it was expedient to use it to "publicly address" the number of people. (Matt 5:1)
When Jesus again addressed a multitude, He pushed off the shore in a boat to "publicly address" the number of people, the boat was "expedient" to address the people...
Today we use electricity and a microphone to "publicly address" the people, it is like the boat, and the mountain "expedient" to address the people, it does not change the message.
Again, please show me where in the bible, on this earth, where the NT church from the day of Pentecost until today used instrumental music other than the voice and the heart, so I can use it too...
