A college student was in a Philosophy class, where a class discussion about whether or not God exists was in progress.
The professor had the following logic: "Has anyone in this class heard God?"
"Has anyone in this class touched God?"
Again, nobody spoke.
"Has anyone in this class seen God?"
When nobody spoke for the 3rd time, he simply stated, "Then there is no GOD."
The student did not like the sound of this at all & asked for permission to speak. The professor granted it & the student stood up & asked the following questions:
"Has anyone in this class heard our professor's brain?"
"Has anyone in this class touched our professor's brain?"
"Has anyone in this class seen our professor's brain?"
When nobody in the class dared to speak, the student concluded,
"Then, according to our professor's logic, it must be true that our professor has no brain!"
Pro 26:5 (JPS): “Answer a fool according to his folly, lest he be wise in his own eyes.”
Heb 11:1 (KJV): “Now faith is the substance of things hoped for, the evidence of things not seen.”
