When Christ was here on earth and the Holy Spirit was not yet given, the demons were subject to the Apostles (and also to those who were not even believers or followers of Jesus Christ)-in the name of Christ only [Matthew 9:38, Mark 9:38, Luke 9:49, Luke 10: 17].  But, the question is: Can anyone use the name of Jesus alone to perform miracles today, or does the scripture mandate any other condition under which one can perform miracles with the name of Christ?

We know that while Christ was still here on earth, we didn't  need any other power or anyone else to empower us to fulfill our calling of [1st Peter 2:9], or cast out devils, because Christ the God-Man dwelt among us, and all we needed was His name only. But after He had laid the foundation of preparing souls for God's kingdom, and His mission was completed, He handed over the work of perfecting and empowering the saints to the Holy Spirit-until He (Christ) returns. So, today, not only must we be saved in Christ and have a relationship with Him, we must also be filled with the Holy Spirit and have the gift of healing and working of miracles (given only by the Holy Spirit-1 Corinthians 12: 9-10) to be able to perform miracles. I make this claim because Christ himself instructed the disciples to wait in Jerusalem until the Holy Spirit came upon them to empower them [Luke 24:49, Act 2:8, John 14:16, 14:26, 15:26, 16:7]. If the only power they needed after He left was His name alone, they wouldn't have been instructed to wait for another power. The people who tried to use the name of Christ alone without the power of the Holy Spirit after Christ left this earth were bruised and broken by the same demons they were trying to cast out [Act 19:13]. This lack of Holy Spirit power today explains the proliferation of false miracles and failed prophecies of today's professing pastors, evangelists, prophets, and Christians in general. In other words, the devils and the deadly diseases they are trying to cast out are saying to them: "Jesus I know, and Paul I know; but who are ye?" [Act 19:15]. If the Apostles were not filled with the Holy Spirit, there was no way they would have been able to raise the dead, heal the sick, cast out devils, and escape the dangers they encountered after Christ left this earth.

But you may ask: How about the authority given to the 12 apostles by Christ Himself in [Matthew 10: 5-8, Mark 3: 14-15], the promises of Christ Himself in to the church in [Mark 16: 17-18, and John 14: 12-14, John 16: 23-26], and the authority permitted unbelievers in [Mark 9:38, Luke 9:49]? If you study these verses carefully, you will notice that this authority was in the name of Christ only while Christ was still here on earth with them (confirmed in Luke 10:17). There are no written accounts of miracles being performed in the name of Christ only by anyone not filled with the Holy Spirit after Christ left this earth. All the miracles ceased-until the Holy Spirit came to empower them.

So, anyone who claims to be performing miracles in the church today must show us "irrefutable" evidence of being filled with the "real" Holy Spirit of God because, the Holy Spirit is the one that gives the gifts of healing and working of miracles, and you cannot have these gifts if you don't have the Holy Spirit that gives them.
