Should This Man Say “Amen!”

A man went for an HIV test on a Friday. He was told to come back for the result the following week.
That weekend, the man went to church. The pastor made some prophetic declaration to the congregation, “Whatever you are hoping for shall be positive in Jesus Name!”
As the whole congregation responded “Amen!” The man stood and shouted, “No! I reject it in Jesus name. My result shall be negative!”

Assuming you were present in the church that day, what would be your own view about the man’s reaction?
