Religion has always been a tool for control and the bible was written by the controllers.
How do you know it wasn't the controlers that taught you that. Perfection is reached by seeing an example and then being able to do the same. In real terms the qualities mentioned would have trees and rocks obey your voice if you are shown how to do that then you will be able to do it also. That is how 'landscaping will take place as mankind spreads out into the new earth. The end goal is more pastures for the ones that man will have dominion over. Their 'guides' are already in a perfected state so any 'advice will be good advice'.
Joh:5:19:
Then answered Jesus and said unto them,
Verily,
verily,
I say unto you,
The Son can do nothing of himself,
but what he seeth the Father do:
for what things soever he doeth,
these also doeth the Son likewise.
The last MB hit I listened to was 'Had to fall in love.' and I could turn it into a hymn based on that but the reason I still listen to it after the lyrics are understood comes from the music that goes with it. While that song has the churchy sounding style and the guitars are windy types over electric (as in War of the Worlds) but the part I listen to is the softly blown harmonic for that very reason. There are a few spots where it is almost solo but there are other times it is almost not even heard. Bringing that part to the front although a better class of source and mixer would be needed.
For what you get out of it is something that would come your way even if you were a stranger to music and the relaxing part of music should not be totally ignored. lol
Since you are connecting to a band almost 45 years from the past means it is a chance event rather than something you and they could intentionally set into motion.
Christianity is a game of connect the dots. 3500 random verses that tell a single story if you can pick and choose which part is the 'right part'. Close means you shouldn't even play. That is based on the size of the number of words in said book. Exact is relative, if I was to ask you to define what God has to say about 'grace' you should type that into your NT search bar and the 'hits' all contain one verse from a passage. If you read those 24 verses you should have some idea about what it is and how it works. In the next phase you read the passage the verse comes from and apply any needed changes. That would include a 'God forbid' when the question of more sin brings more grace question. You are now an expert on the term 'grace' and while you don't have to memorize the verse you should at least review it to make sure it says what you used to think it said. That is a problem with spiritual growth (or any growth) until you are an expert you have to do a review every now and then. A harmonica in my world would bring a set or unique memories that I would find pleasant to remember. I even do some math to deal with 'supposed experts', if I have a 1/2 hour with them I listen to something relaxing for 45 minutes before the meeting.
I think I'll dust off the song you posted the lyrics for and see if anything else in the piece is part of why it is in the collection to begin with.
A song that mentions heaven is not as detailed as the book about heaven. Think of the post of lyrics as being one page from the Bible and you read the required number (as many times as it takes) you would know all that God had had to say on those subjects.
To understand what musicians think I would have to hear every song ever produced, I don't see that happening really.
