BDBD is Acts 28:17-31

   Paul used this opportunity to tell the Jews in Jerusalem that Jesus is the Messiah. He used many Old Testament verses. Some believed. Others did not. Such is the case with anyone who hears the truth. We either accept or reject.
   How is a callous heart softened? Is there any hope for someone who hears the truth and rejects it? As long as a person breathes there is hope that they will accept God’s word. God slowly works on all callous hearts, and all have callous hearts before they accept.
   A raw lump of clay is hard. The potter kneads the lump to soften it. When it is soft enough the potter can form it into a beautiful vase. Every lump of clay has a beautiful vase in it. If it will not soften, he throws it away.
