There is a danger when folks avoid teaching. Instead of striving to preach the Truth in all its purity, they will tone it down so as to make it more palatable to the unregenerate. Impelled by a single force, moving in one fixed direction, thier object is to make conversion easy; and therefore, favorite passages (like John 3:16) are dwelt upon incessantly, while others are ignored or pared away. It inevitably reacts upon thier own theology; and various verses in the Word are shunned, if not repudiated. What place will he give in his thoughts to such declarations as, "Can the Ethiopian change his skin, or the leopard his spots?" (Jer. 13:23); "No man can come to Me, except the Father which hath sent Me draw Him" (John 6:44); "Ye have not chosen Me, but I have chosen you" (John 15:14)?
He will be sorely tempted to modify the truth of God's sovereignty, of Christ's redemption, of the imperative necessity for the super-natural operations of the Holy Spirit. He will preach to tickle the itching ears and nothing more.
Preaching is useless if folks do not understand what is being preached. Many harp on simple verses yet go to the extreme to avoid telling them what they are being saved from. They repeat John 3:16 over and over but that has little meaning to those who dont know what sin is and its relation to Gods Holiness. We can go around and tell folks that Jesus loves them and they they may be saved, but until they understand the necessity for being saved, they will not see the love Jesus has.
We must preach the truth fully, without holding back. We must be ready to teach as well. We must be prepared for the questions fro the sincere seeker. We jst remember to do it in earnest and with an apparent motivation of love for one another. Not to browbeat and tear another down.
