Scripture you base this on?
Acts 2:37
Now when they heard this, they were pierced to the heart, and said to Peter and the rest of the apostles, “Brethren, what shall we do?” Peter said to them, “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit. For the promise is for you and your children and for all who are far off, as many as the Lord our God will call to Himself.”

No! Never! The greatest miracle is the work of God accomplished through the preaching of the Word as applied by the Holy Spirit. The greatest power of God is not a room trembling. The greatest power of God is not even the removal of a mountain. The greatest power of
God is in the pricking of a heart. There is more power of God in His pricking of the heart than in His holding of the world in its place. This is the miracle of grace. Is it true for you?
The change was not produced by a clever, psychological ploy; not by persuasive appeal; not by skillful crowd manipulation; but by the Word of God preached from faithful lips and
brought by irresistible grace through the Holy Spirit. Is this the effect of God’s Word preached upon you? Not indifference, not polite neutrality, not complacency. But pricked in the heart?
The text no where states the action was done by God, pierced to the heart, um perhaps here is a novel concept maybe it was their conscience. Calvinists don't believe that a person can hear the Gospel and be moved, no they are born with an inability to respond so god can be magnified in their inability. Sounds like an insecure god to me.
Same ole doctrine with different words to express it. Eisegesis its finest.
