"And when he had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each holding a harp, and golden bowls full of incense, which are the prayers of the saints. And they sang a new song, saying,
“Worthy are you to take the scroll
and to open its seals,
for you were slain, and by your blood you ransomed people for God
from every tribe and language and people and nation,
and you have made them a kingdom and priests to our God,
and they shall reign on the earth.”
Above we have true spiritual, perfect, sinless worship in Heaven, they are not singing from the pslater, they are playing music!
How dare men say that this sort of worship is false on earth, when it is perfect in Heaven!!

Jesus and the disciples worshipped in the synagogues but there is no reference to the banning of music or instruments in scripture. I am sure they did not use the classical hymn music of today but music from their culture that they could feel comfortable in using to sing praises unto God.

The following comes from the Hymnal on Sermon audio.
"The hymn "Be Thou My Vision" is a prayer that may accept Christ as our pattern, our hero, our ideal. Our adoration is told in these names and phrases: Lord of my heart, my best thought, my wisdom, my true word, my great Father, mine inheritance, my treasure and finally, heart of my own heart.

The original version of this hymn was written by an unknown Irish Christian in the eighth century. The tune is an Irish folk melody."

The early church sang hymns - not just psalms. Some are recorded in the letters. Others are found in our hymn books.
