Preaching to Harden Hearts

Part of Isaiah's job was to preach to harden hearts. See Isaiah 6:9-10. For those who would repent, wonderful! For everyone else it was God giving them one last chance. Either way, Isaiah's time and effort was for the Lord. This should help us in our outreach efforts today as we remember that it's not our job to sell people on Christianity. We are simply called to be God's messengers and the Holy Spirit will either work faith in hearts to help them see and understand or, if they continually reject the Word, he will harden their hearts so they are literally blind to the truth that to us is so obvious.
