Humility will prevent us from being the stale Christain God revealed to Isaiah in chapter 6, verses 5-10
Then I said: Woe is me, for I am ruined, because I am a man of unclean lips and live among a people of unclean lips, [and] because my eyes have seen the King, the LORD of Hosts.  Then one of the seraphim flew to me, and in his hand was a glowing coal that he had taken from the altar with tongs.  He touched my mouth [with it] and said: Now that this has touched your lips, your wickedness is removed, and your sin is atoned for.  Then I heard the voice of the Lord saying: Who should I send? Who will go for Us? I said: Here I am. Send me.  And He replied: Go! Say to these people: Keep listening, but do not understand; keep looking, but do not perceive.  Dull the minds of these people; deafen their ears and blind their eyes; otherwise they might see with their eyes and hear with their ears, understand with their minds, turn back, and be healed.
"God sends Isaiah to foretell the ruin of his people. Many hear the sound of God's word, but do not feel the power of it. God sometimes, in righteous judgment, gives men up to blindness of mind, because they will not receive the truth in the love of it. But no humble inquirer after Christ, need to fear this awful doom, which is a spiritual judgment on those who will still hold fast their sins. Let every one pray for the enlightening of the Holy Spirit, that he may perceive how precious are the Divine mercies, by which alone we are secured against this dreadful danger. Yet the Lord would preserve a remnant, like the tenth, holy to him. And blessed be God, he still preserves his church; however professors or visible churches may be lopped off as unfruitful, the holy seed will shoot forth, from whom all the numerous branches of righteousness shall arise. " ~ Matthew Henry's Commentary
