I think some imagine that God is bored in heaven and to liven up the scene on earth he sprinkled out some excitement in miralces signs and wonders. The bible has ONE prominent reason for miracles signs and wonders from Moses to the Apostles - To confirm the Word spoken/written as the Word of God. A. Moses the first miracle worker of the bible Ex. 4:1 ¶ And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice: for they will say, The LORD hath not appeared unto thee. 2 And the LORD said unto him, What is that in thine hand? And he said, A rod...... 5 That they may believe that the LORD God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared unto thee. B. Elijah the Second Miracle Worker of the Bible 1 Kings 18:36 And it came to pass at the time of the offering of the evening sacrifice, that Elijah the prophet came near, and said, LORD God of Abraham, Isaac, and of Israel, let it be known this day that thou art God in Israel, and that I am thy servant, and that I have done all these things at thy word. C. Jesus Acts 2:22 Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know: Joh 10:25 Jesus answered them, I told you, and ye believed not: the works that I do in my Father’s name, they bear witness of me. Joh 10:37 If I do not the works of my Father, believe me not. Joh 10:38 But if I do, though ye believe not me, believe the works: that ye may know, and believe, that the Father is in me, and I in him. D. The Apostles: Heb. 2:3 How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him; 4 God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will? Conclusion: Miracles signs and wonders have the PRIMARY design to CONFIRM the spoke/written word of God to be truth. SATANIC MIRACLES have the very same purpose in reverse. To use AUTHENTIC POWER of miracles signs wonders to confirm ERROR as truth and thus be used to DECEIVE people. 2 thes. 2:9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders, Mt. 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. 25 Behold, I have told you before. Mt 7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? How to tell the difference between the true and false miracles? 1. BOTH are genuine signs and wonders and REAL power 2. The distinction is the TEACHING being confirmed. 3. Demonic power in the name of Christ (Mt. 7:22) confirms FALSE doctrine CONCLUSION: True miracles signs and wonders confirm TRUTH and TRUTH is ultimately tested by God's Word not by miracle power: Isa. 8:20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. 1 Jn. 4:1 ¶ Beloved, believe not every spirit, but try [test] the spirits whether they are of God: because many false prophets are gone out into the world..... 6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error. Hence, if the miracle worker or their theological advocates tell you such absolute nonsense that Hell has a "WELCOME" sign over it you can be assured this is a real or fake miracle that confirms ERROR and thus originates form the "spirit of error." If they teach false doctrine their miracles signs and wonders are DEMONIC in origin.
