I'm sorry my friend, but I won't accept this opinion. "The OT was physical" is a gross over-generalization. There is much in the NT that is also physical (Matthew 25, just off the top of my head). It is about what we do that that praises God.
It ws not me who made this "over generlaztion" the Bible tells us the things uner the Old law were a shadow, but the true image is spiritual. Heb 10:1-f. Col 2:14-f. These things represented the true, they were a shadow of what was to come. What came was the "true worshipers" that worship in spirit and in truth.
I never meant to imply there is not anything physical in the NT, that would be absurd, we live in a physical world.
I meant the the things that foreshadowed were not spiritual themselves, but represented the spiritual.
For example.
The Temple - a physical building that was said to be God's dwelling place.
NT - The temple is now spiritual, made up of Christians, God's dwelling place, there is not a physical temple anymore that God "dwells in", Yet that does not mean Christians do not meet in physical building, yet the Building is just a building, the Christian is the temple, the spiritual body of Christ.
The Tabernacle - the holy room, only the physical high priest could enter.
The NT, the holy room is heaven, and Christ our spiritual High priest, has entered as the forerunner for us all.
The lamb without blemish for sacrifice. It was a physical lamb without any physical spots.
Jesus is that lamb spiritually, he not literally a lamb. He was not literally without blemish(or if he was that's beyond the point) he was "un-spotted" from the world, meaning he was sin free.
These things were all physical things that looked forward to the spiritual.
The burning of incense in worship. Was the act of literally burning incense, yet the NT is shown this symbolized the prayers of the saints - Revelation.
So we no longer burn incense we pray as a sweet odor to God.
It was the same with the use of stringed instruments and other types. It symbolized the Christians who "pluckes the strings of the heart", the literal meaning of "psallo" in Eph 5:19.
We are to make melody in our heats - again this is spiritual. Not only do we see anywhere in the NT the early church using them, we also have the command to "sing".
Just as we understand why animal sacrifice, the temple, the tabernacle, burning of incense all ceased because of what they symbolized, we also should use the same reasoning with mechanical instruments.
I am not Methodist, but this quote surprises many Methodists:
John Wesley (1703-1791), a father of Methodism
"I have no objection to instruments of music in our worship, provided they are neither seen nor heard."
The fact is using instruments is something still new. Only in the last couple hundred years.
Also, I'm confused by your reference to worship when we are on the topic of praise. To me they have always been two different things (they are different words). To me, and who I read and interpret, worship is a matter of reverence, praise is a matter of thankfulness.
praise is a part of worship. It glorifies God. it is done with reverence and fear, Col 3:17. Yet the entire act of worship, includes praise, prayer, communion, etc.
We are to these according to what God says, not according to what pleases us. Not saying that's what you do, I am just saying this in general.
