Of course you are right, but you are right because God has made it so. The carnal person alone cannot really know truth. Consider:The truth is knowable otherwise Jesus would not have suggested it. John 8:31-32
"Pilate saith unto him, What is truth?... " John 18:38
Pilate did NOT know the answer to his own question not realizing that the "truth" was standing right in front of him.
Anyone can know the truth, but it must be, I believe, approached along the pathway of faith.
