For false messiahs and false prophets will rise up and perform signs and wonders so as to deceive, if possible, even God’s chosen ones.
In the book of Acts, we will see the apostles preaching the Word of God and the accomplishments of the Son in living, dying and rising from the dead. This message will be accompanied by signs and wonders.
Signs and wonders are not in themselves indication of authenticity as we see here.
So listen to what the miracle workers say. To whom does the miracle worker seek to bring glory? Does the wonder accompany an impassioned plea to repent and believe in the Good News of Jesus Christ?
Do not merely be stupefied by the wonders, but ponder what message accompanies the wonders. This will be a safeguard against accepting or believing false messiahs and prophets.
