As a teenager I saw on television a movie called "The Invisible Man". A scientist had developed a process that rendered his body transparent or invisible. To indicate this invisible man the camera would follow an invisible space, doors would open and close, and then the man would wrap himself in cloth to render himself with a visible representation of his body when he wanted someone to actually recognize his presence. While invisible he could easily listen to other conversations, examine contents of a room, and take other actions unobserved there was a side affect of the process. Repeatedly using the process to remain invisible the man was actually making himself go insane.
There are two general overall means of communication, personal face to face and written. Today a third means is video, but with advances of other technology even the video posts may be artificially produced making a frw of them very convincing, but untrustworthy. Before the advent of electronic written communication there were hand written letters, post cards, and printed books. With electronic communication a most popular means is "texting". When you communicate by written means there are no outward signs for a person to observe from your bodily actions that may well influence your understanding of the words. In fact one of my favorite quotes about that form of communication is:
Texting is a brilliant way to miscommunicate how you feel, and misinterpret what other people mean.
The "invisible man" actually exists as the greatest part of our lives. When we write unless describing bodily feature or action the invisible man is all the other person may hear or know. It truly is like communicating with a blind person. They hear you, but cannot see you. Our thoughts and our intended meaning of our thoughts actually make us invisible. A once popular phrase in some cultures was "Children should be seen, and not heard" generally meant children are to remain invisible, especially since adult eye level was over the heads of most children. But even in face to face communication we are warned:
When thou sittest to eat with a ruler, consider diligently what is before thee, And put the knife to thy throat, if thou be a man given to the appetite. Be not desirous of his dainty meats: for it is a deceivable meat.
Proverbs 23:1 - 3 GNV
Deceitful meat, food that entices you to be willing to say things you shouldn't, maybe even speculate rather than only present what can be soundly verified.
When we present ourselves to a new acquaintance whether in written form or in person we don't typically begin with expressing the characteristics of our lives others find reprehensible and repulsive, but rather we put our best foot forward in whatever means of communication we may use. It is only a matter of time before the genuineness or deceitfulness of your communication is determined.
As to being invisible as a person, yes, most of who we are is invisible. This beones even more true when we see ourselves as having both the old man and new man as described in Colossians 3 and other places in the New Testament. We may even think of angels (messengers) and demons or devils (fallen messengers) as not like us because they are mostly invisible to us. But we are told that sometimes we entertain angels unaware that they are angels. So many are reported appearing throughout the Bible and yet today we often think of them as nothing more than invisible, therefore mystical beings. In reality all of who we are is as invisible as they are.
When I am asking myself about Jesus and what His time of communication with His Father was like, did it involve praying a psalm, it is true that I must come to a point where I accept that everything about Jesus IS His best foot forward always, the only thing He can put forward. He has nothing to hide. While He did physically go certain places and avoided other places during His ministry on earth He made who He was more and more clear. For some what was so difficult for them when He clearly presented Himself, or represented Himself as the Christ which they couldn't accept when it was surrounded with so much truth they couldn't refute.
Send thy light and thy truth: let them lead me: let them bring me unto thine holy Mountain and to thy Tabernacles. Then will I go unto the altar of God, even unto the God of my joy and gladness: and upon the harp wil I give thanks unto thee, O God, my God.
Psalms 43:3 - 4 GNV
Why giving all this thought about our invisible being? These verses begin with asking God to send light and truth. As I asked myself what they are I realized that from a physical property physics point of view today light is being more defined, but still not entirely known. Referring to light otherwise as what enlightens our minds that falls into the same category as truth. Still even in that Jesus Christ the Word says,
Jesus said unto him, I am that Way, and that Truth, and that Life. No man cometh unto the Father, but by me.
John 14:6 GNV
When this is examined it might be said that the fully God/fully man Jesus was the embodiment of that Way, that Truth, that Life. At the sametime having a body we also recognize that Way, Truth, and Life He was talking about are also invisible. The invisible part of us can go in that Way, it can live by that Truth, and that invisible man of who we are can live in that Life of who He is.
There is a different framework to these next 40 some Psalms, but they still can be sung as songs. With the right understanding every song that can be sung may also be a prayer that can be prayed. May we take time to read, meditate, and examine the Scriptures daily to find what is so.
