Matthew 15 describes a display of supernatural power to the benefit of man and that glorified God.
30 And great multitudes came unto him [Jesus], having with them those that were lame, blind, dumb, maimed, and many others, and cast them down at Jesus’ feet; and he healed them:
31 Insomuch that the multitude wondered, when they saw the dumb to speak, the maimed to be whole, the lame to walk, and the blind to see: and they glorified the God of Israel.
Believers seeking fellowship with God and Jesus Christ desire to have miracles in our lives every day. However, living in a world ruled by Satan, it is possible to see counterfeit supernatural happenings. thewayinternational.com/genuine-versus-counterfeit
II Corinthians 2
11 Lest Satan should get an advantage of us: for we are not ignorant of his devices.
One deception exposed as counterfeit in the scriptures is the false idea that there could be consciousness after death. I Samuel 28:7-25 Details the record of the woman of Endor sought out by Saul. archive.org/details/aredeadalivenow0000wier/page/n5 She was controlled by an evil "familiar spirit" and impersonated the dead Samuel. Saul was deceived and convinced he had spoken with Samuel, disturbing him in his grave. He did not experience God's power in this situation.
By continuing in the scriptures, we can enjoy miracles that glorify God. In sharing our knowledge of the truth, we can also help our fellow man not be deceived by the counterfeit.
