(John 9:39) "And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind." The above verse teaches us about the importance of believing God's Word when we hear it. Naturally, all men are blind to the truth of God because of their sin nature. So, to open the eyes of men God chose the foolishness of preaching His Word (1 Cor. 1:21). However, the problem with man is in his heart. Too often the Word of God is preached and because a man's heart is hard or indifferent to the message or the messenger, he will reject what he hears in unbelief, making himself even blinder and harder. If a preacher is preaching and explaining God's Word, he stands as an ambassador of God. Be careful when you hear God's Word, it's not the preacher's word it's God's. If we will both listen and obey, we will see the truth and that truth will both save us and protect us in this life, but if we reject it be afraid, our disbelief will cause us an even greater judgment. Oh listen, God desires that all men see His truth. (Jn.8:32) "And ye shall know the truth, and the truth shall make you free."
