Somethings to think about.

The argument that they don't use instruments in Jesus's day, is wrong historically. If a tradition of music in worship throughout the Psalm is carried through holy festivals I imagine they would be used. I imagine it would. be used in worship. Such as Psalms 150 where full expression of every kind of holy worship is encouraged. Acapella is still a ministry. Should we seclude it or eliminate it absolutely not. But variety in worship should be encouraged instead.

However order or heart isn't always there. Sometimes we deal with being religious in skill or knowledge of music. God doesn't like a prideful divatisium. I repent of prideful divatisium. We all shouldn't be disrespectful or consider others better than ourselves. We shouldn't boast or glorify ourselves. We shouldn't shove knowledge down someone's throat. Musical instruments add an additional order when done right and take away awkward pauses. We also shouldn't overemphasize order but put the music on the screen having it move with programming and give the overemphasis to the Lord. I'd like to do Acapella with a karaoke set up with 4 part singers. One thing is mainstream doesn't do much acapella so we sing mainstream christian music acapella. Or a gazebo impromptu spontaneous worship where one person starts singing a song sings it through then the audience joins in.Then when it is over a one of the audience person starts the next one.  God has led in both impromptu acapella and impromptu with instruments and singing. I have had miracles where piano and guitars tuned automatically. Music being heard that angels sang and hearing the angels harmony with spiritual ears and the crowd join in their harmony. I've had long sets of songs made in just one recording. If I wrote more music, I wants see God move someone's hands to write music. With guys like Mozart they heard music. They may have heard music by angels.

I have also wrote a theology to baptist baptisizing differently. Look at the age to come to see that Jesus is more than meaning.
