John said to him, “Teacher, we saw someone casting out demons in your name, and we tried to stop him, because he was not following us.” But Jesus said, “Do not stop him, for no one who does a mighty work in my name will be able soon afterward to speak evil of me. For the one who is not against us is for us.
Prior to these verses, we saw the immaturity of the disciples in failing to cast out demons and arguing who was the greatest. And now they possessed a sectarian spirit.
Today, there are some evangelicals who will go around discrediting all charismatics as though they belong to the devil. Some charismatics are merely doing great works in the mighty name of our Lord in casting out demons or prophesying for the good of Christendom. Yet they are discredited like as though they are preaching a false gospel or living in sin.
(Side note : I say some charismatics and not all because I am also disgusted with pagan-like signs and wonders which may be demonic in nature. Such abuse should not be the reason to discredit all charismatics and all spiritual gifts.)
It seemed to me in the above Scriptural passage that the only qualm was those casting out demons were not a team with the apostles. That was all. Jesus our Lord had clearly said that these people who did mighty works in His name were not damaging His name and would surely not speak ill of Him.
(Side note : Though I agree that the signs and wonders performed by the apostles were to substantiate their apostleship, we saw from this Scriptural passage that others, not traveling with Jesus our Lord and the apostles, could also perform mighty works in His name which our Lord did not deny.)
On the contrary, I am wondering today if those, who harbor such critical sectarian spirit, are being influenced by the enemy instead to deprive God of the glory for such works. Matt 5:16.
We must have a good balanced stance. Like for the gift of prophecy, do not despise straightaway. Test all of them and hold fast what is good as exhorted by Scripture. 1 Thess 5:20-21.
