God has not called us to be idle.  Just like He had made Ezekiel as a watchman over Israel, He has made us to be a watchman over our area and our lives as well.  We have the answer to the questions, we have the answer to the problems, we have Jesus.  Our responsibility is to spread the good news of Jesus, and leave the results up to Him.  Its a personal choice for someone to accept Him into their lives.
