No it's not. I've been taught by the Lord Himself about the anointing and His Spirit. If you think that whenever God showed up and people fell down that there was nothing 'sensed' in their spirit man, you are sorely mistaken.
That is not the anointing that Jesus spoke about in the synagogue. It may very well be a work of the Spirit, and then again it could be of the flesh because folks think that they are more spiritual if they fall over. If that is all that happens in church and no one gets saved, healed or delivered, then the church is just a religious club and the anointing is absent.
It is clear that you are attempting to use your carnal mind (which cannot understand spiritual things) to try and explain something which is spiritual. You cannot logicalize or make sense of the anointing or the things of the spirit with your carnal logic and understanding, try as you may.
My views are on the basis of what Jesus said about His anointing. He said nothing about people falling over under any kind of spiritual influence as being an anointing of the Spirit. Some people get so "spiritual" they depend on feelings and impulses and ignore what the written scriptures actually say.
Again you are trying to make logical sense with your carnal mind of spiritual things, which is impossible. When the Spirit of the Lord showed up, when spiritual beings showed up, and when Jesus showed up, there were often all kinds of physical manifestations in the humans around them as a result.
God gave us a brain, and He gave us a book to study. When Jesus made statements, He meant what he said. Some try and see "deeper" meanings in the subtext of Scripture and they miss what is actually being said. We are supposed to accept the obvious meaning of what is written. We are supposed to use our logical minds to determine what is being taught in Scripture. If you read the text of the Gospels, the only physical manifestations that occurred when Jesus showed up were demonic. Other manifestations were that people got healed. No one fell over, except those who came to arrest Jesus, and they were not believers in Him. A lot of the quaking, shaking, jerking and falling over in some churches have no support in Scripture because there was nothing written like that in the book of Acts. I would rather believe what Jesus said about the anointing than anyone else or any inner voice. Jesus did say that the Holy Ghost anointing would teach us all things. So that is another aspect of the anointing. It teaches us about the things of God and leads us into all truth; but that truth has to be totally consistent with teaching that runs through the thread of Old and New Testament Scripture.
There are many people who cast out demons and heal the sick in Jesus' name whom are not anointed at all. God's stamp of approval is not on them. Look at Matt 7:22-23
Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
The Scripture you have quoted does not include healing the sick, so that is no included in Jesus' warning. You will notice that these people are saying what they were doing. A truly anointed ministry will point people away from him and direct them to Jesus. They will say that it is Jesus who is doing the work not them. Kathryn Khulman's response to a woman who thanked her for her grandson's healing was. "It wasn't me. I didn't do anything. Jesus did it all. Thank Him." In the reference, Jesus was not talking about born again Christians who are depending on His work on the cross to justify them. Truly anointed ministries will tell the Lord that they did their best for Him and acknowledge that their only qualification for being in the Book of Life was that Jesus died on the cross and shed His blood for them.
It is the prayer of FAITH that heals the sick -- Jesus was the most annointed man who walked the face of the earth and yet there were towns in which He could do NO MIRACLES at all. So according to your logic you would say Jesus lost His anointing during those times? ..No, brother, Jesus never lost His anointing. The miracles and healings couldn't be done because there was no FAITH in those towns.
There is no measure of anointing. A person is either anointed or not. Anointing is authority to do something. An anointed ministry of healing has the authority of God to do the work and the Holy Spirit recognises that authority and works through him to accomplish God's purpose for the anointing. It is true that Jesus had the Spirit without measure, therefore His anointing was more extensive. Yet He said that the works He did we would do, even greater works. So Jesus can anoint a person to do greater works than Jesus did! But the anointed person has to remain humble. Moses failed to get to the Promised land because he struck the rock instead of speaking to it. Then he said, "Look at what Jehovah and I can do!" Because he included himself, he missed out, because he tried to share God's glory. The ones whom Jesus will reject are those who attempt to share His glory in what they do for Him.
These truths prove your theory about the anointing to be incorrect.
