Isaiah 28:25-27 (c) Probably in this story the wheat represents the Gospel message, while the other four grains represent other truths that should and do accompany Gospel preaching. In all of our preaching and teaching the good news about the rich provision the Lord JESUS makes for the soul should have the principal place. Other things that accompany this message may be prophecy, history, personal experience, godly living. Certainly there are many such truths to be found in all good teaching and preaching, but these are not to replace the Gospel of GOD's grace.
