Where does Jesus say to use our own common sense? He tells us to believe HIS WORD. Apostle Paul bitten by a venomous snake and shook it off. Never used medicine, just believed God. Other nonbelievers waited for him to die. But didn't happen. He trusted in the WORK OF JESUS ON CROSS.
Paul and the disciples were directly chosen as prophets by God. They had seen God.
Tell you waht. I'll get the snake. Will you let it bite you?
