You are going from one extreme to another!
Christianity is more than a message, it's a life motivated by joy and love.
These verses have already been referred to:
Eph:5:19: Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord;
Col:3:16: Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
I would add:
"thou that inhabitest the praises of Israel." (Ps.22:3)
Instruments were always a part of worship and there is nothing in the NT to say that should stop.
"Praise him with the sound of the trumpet: praise him with the psaltery and harp. Praise him with the timbrel and dance: praise him with stringed instruments and organs. Praise him upon the loud cymbals: praise him upon the high sounding cymbals. Let every thing that hath breath praise the Lord. Praise ye the Lord." (Ps.150)
To people that say the NT doesn't specifically mention instruments therefore we shouldn't use . . . do you forbid the use of cars and computers, oh and electric light?
Anyway, the NT *does*:
Rev. 5:8: And when he had taken the book, the four beasts and four and twenty elders fell down before the Lamb, having every one of them harps,
Rev. 14:2: And I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder: and I heard the voice of harpers harping with their harps:
You are right to want orderly meetings though.
Please have a close read on 1 Corinthians 14 . ..
1Cor. 14:37: If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord.
Few churches do what it says there!!
In
