I’ll tell you more of this picture story about the builders. Good builders build with really good things like gold, or silver or jewels. But other builders don’t work properly, they don’t care, they only use wood, or grass or leaves. If a fire comes, the houses made of wood, or grass or leaves will burn up, but the houses made of gold, or silver or jewels will stay good. So you can know which builders did a good job. Christian workers are like those builders in the picture story, some Christian workers do a good job and tell God’s word properly and some don’t do a good job.
