I have noticed over the years that some people cannot hear the truth. Whether it’s a New Testament commandment such as 1 Corinthians 14:34-35 or God’s continuing promise of miracles displayed in James 5:14-15 they simply cannot hear it.
It begs the question why?
Perhaps they are attached to errant doctrine. Perhaps they are having difficulty accepting the truth. Perhaps there is an issue with understanding.
Indeed, perhaps there is some mitigating circumstance, but there is a worse case scenario. It is explained by Jesus in John 8. John 8:43-44, 47 KJV says, Why do ye not understand my speech? even because ye cannot hear my word.  Ye are of your father the devil… Jesus continues in John 8:47 KJV, He that is of God heareth God’s words: ye therefore hear them not, because ye are not of God.
Not being all knowing it is possible we go too far if we surmise the worse concerning others, but it is something that requires strong consideration. In the least it is a warning flag.
