Ephesians 5:19 Speaking to yourselves in psalms and hymns and spiritual songs,
singing and making melody in your heart to the Lord;
Colossians 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.
No "worship leaders" or performances there.
"No "worship leaders" or performances there."
No, but that is not describing a modern worship service. This is one of the scriptures used by the Church of Christ to make the case that using ANY musical instruments in church is against the word of God.
Regarding this sort of stuff, there is just way too much nit-picking, and that nit-picking is in the "spirit" of exactly what the religious leaders of Jesus' time were trying to do.
One can obey the scripture you quoted on one occasion, and then do other things, like have a worship service or Sunday school class on another occasion.
Keep in mind that I am just talking about how services are run, not the content of the words in those services.
