Why are some pictures of fanatics and errant people always brought up whenever something that can be done the correct way is mentioned?
The truth is that speaking the name of Jesus in faith that God will work, is not putting faith in our sound waves as though God need not be involved. God's Word is powerful enough to create. I believe speaking the name of Jesus in genuine and correct faith actually moves God to work and accomplish a supernatural feat. We are labourers together with Christ. We cannot do anything without Him. He's the vine that supplies the life into us the branches.
Invoking His name is part of what is required to see God move, just because He said so! Speaking His name in and of itself does nothing, as is evident from the exorcists who spoke His name in
Acts 19 and accomplished nothing.
But when a person speaks the name of Jesus to cast out devils, for example, something actually happens supernaturally by God that would not happen if the name was not invoked. Again, do not confuse this with mere sound waves as though God's power is not involved. God sees us speak His name in faith that we are one with Him by the work of the cross, and HE STEPS IN AND WORKS! That is a far cry from "abracadabra".
The demons feel a power overwhelm them and they leave.
Speaking the actual name "JESUS" was implied when Jesus told us to cast out devils in His name. The reference to "in my name" is found in the command to cast out devils as well as to baptize people. That does not mean the casting out is common as though we cast out sin. Far from it. It simply means baptizing people must include the actual utterance of the name TO SEE GOD'S POWER WORK. God steps in and no sins are cast out (lo) but He puts us into the death of Christ and operates a spiritual circumcision in our hearts to remove the body of sins of the flesh, and not physical flesh as in natural circumcision. God actually does something.
The actual working of God in His power is what is common in casting out devils while speaking Jesus' name as well as baptism while speaking that name. The commonality IS NOT something cast out, as Originalist thought I implied.
Because Jesus commanded us to cast out devils in His name as well as baptise in His name, and because we read Paul actually invoking that name
(whether the demons knew him or not) in obedience to Christ's command, we know that actually invoking the name must be administered in baptism.
We never see Paul cast a devil out without invoking the name Jesus, as you implied can be done, Originalist, if the devils already know us. They knew Paul. He still used the invocation.
Again, GOD DOES A WORK when we invoke that name. He does a work that simply He does not do when the name is not invoked. One brother agreed he would not seek to attempt to cast out a devil without invoking the name. By the same token, I would never seek to baptize someone without invoking the name. It's not the sound waves that do anything. It's HIS NAME THROUGH FAITH IN HIS NAME that moves GOD TO DO THE WORK described in
Romans 6 and
Col 2:11-12, and the remission of sins in
Acts 2:38. And without repentance as well, it cannot happen.
