God called the prophets to speak His Word. He warned them, do not add to it, do not take away from it. God’s Word through the prophets was often a word of warning and rebuke about sinfulness and repentance. The prophets were despised, rejected, and usually killed by God’s people. Which is also what happened to Jesus – the Word of God incarnate! He was rejected by mankind, but His sacrifice for the sins of the world was accepted by God!
