The Word of God commands believers to "try the spirits" to see what kind of spirit is energising, leading, directing people (1 Jn 2:1) because false doctrines originate with spirits - demonic spirits (1 Tim. 4:1).
The Spirit of God is characterized as the Spirit "OF TRUTH" and the command to "try" the Spirits is a test of "truth" - 1 Jn. 4:6.
The Bible is the "word of truth" as Jesus asked the Father to sanctify his disciples by the truth and "thy word is truth."
Hence, the same test in the New Testament is the same in the Old Testament "if they speak not according this word it is because there is no light in them" - Isa. 8:20.
This is particularly true in regard to those whose perform authentic miracles and their prophesies do come to pass as miracles and fulfilled prophecy are not the final test of truth:
Deut. 13:1 If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,
2 And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them;
3 Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul.
4 Ye shall walk after the LORD your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him.
When a person does miracles and wonders and predicts things that come to pass but their teaching does not harmonize with God's Word those miracles, signs and wonders are called "LYING" wonders because they do not confirm the truth of God's Word but confirm FALSE doctrines which originate from demonic spirits (1 Tim. 4:1).
The so-called Pentecostal/Charismatic movement teaches every false doctrine under the Sun and all claim the same experience - baptism in the Spirit and speaking in tongues. It is a demonic led movement and their doctrines prove it as well as the mass confusion among those claiming the same baptism and exercising the same kind of escatatic utterance they call "tongues."
Can true christians be involved in a demonic movement? Read Revelation 18:4
