Nearly every prophet in the Old Testament had a specialty.  Their ministries were each characterized by some part of their individualism, or their specific calling or gifting.  While one was a worker of miracles, another would be a seer of things to come. God specifically prepared them for the need of their days.  In the same way, He equips the saints of God today with special characteristics.  God has specifically called and equipped YOU for the job He has chosen you for, in His Kingdom!  There's a similarity in each of us too though. The underlying quality that he looked for in each prophet, and that he looks for in each of us today, is faithfulness to Him and His word!
