Pride disguises itself as many things and we are not able to discern it apart from God's light. I want to share with you where I found it hiding in my life and give some Bible examples.

Pride can disguise itself as great spiritual discernment or certainty.

1 Kings 22:1-28 And they continued three years without war between Syria and Israel. And it came to pass in the third year, that Jehoshaphat the king of Judah came down to the king of Israel. And the king of Israel said unto his servants, Know ye that Ramoth in Gilead is ours, and we be still, and take it not out of the hand of the king of Syria? And he said unto Jehoshaphat, Wilt thou go with me to battle to Ramothgilead? And Jehoshaphat said to the king of Israel, I am as thou art, my people as thy people, my horses as thy horses. And Jehoshaphat said unto the king of Israel, Inquire, I pray thee, at the word of the Lord to day. Then the king of Israel gathered the prophets together, about four hundred men, and said unto them, Shall I go against Ramothgilead to battle, or shall I forbear? And they said, Go up; for the Lord shall deliver it into the hand of the king. And Jehoshaphat said, Is there not here a prophet of the Lord besides, that we might inquire of him? And the king of Israel said unto Jehoshaphat, There is yet one man, Micaiah the son of Imlah, by whom we may inquire of the Lord: but I hate him; for he doth not prophesy good concerning me, but evil. And Jehoshaphat said, Let not the king say so. Then the king of Israel called an officer, and said, Hasten hither Micaiah the son of Imlah...And the messenger that was gone to call Micaiah spake unto him, saying, Behold now, the words of the prophets declare good unto the king with one mouth: let thy word, I pray thee, be like the word of one of them, and speak that which is good. And Micaiah said, As the Lord liveth, what the Lord saith unto me, that will I speak. So he came to the king. And the king said unto him, Micaiah, shall we go against Ramothgilead to battle, or shall we forbear? And he answered him...I saw all Israel scattered upon the hills, as sheep that have not a shepherd: and the Lord said, These have no master: let them return every man to his house in peace. And the king of Israel said unto Jehoshaphat, Did I not tell thee that he would prophesy no good concerning me, but evil? And he said (that is Micaiah), Hear thou therefore the word of the Lord: I saw the Lord sitting on his throne, and all the host of heaven standing by him on his right hand and on his left. And the Lord said, Who shall persuade Ahab, that he may go up and fall at Ramothgilead?...And there came forth a spirit, and stood before the Lord, and said, I will persuade him. And the Lord said unto him, Wherewith? And he said, I will go forth, and I will be a lying spirit in the mouth of all his prophets. And he said, Thou shalt persuade him, and prevail also: go forth, and do so. Now therefore, behold, the Lord hath put a lying spirit in the mouth of all these thy prophets, and the Lord hath spoken evil concerning thee. But Zedekiah the son of Chenaanah went near, and smote Micaiah on the cheek, and said, Which way went the Spirit of the Lord from me to speak unto thee?...And the king of Israel said, Take Micaiah, and carry him back unto Amon the governor of the city, and to Joash the king's son; And say, Thus saith the king, Put this fellow in the prison, and feed him with bread of affliction and with water of affliction, until I come in peace. And Micaiah said, If thou return at all in peace, the Lord hath not spoken by me.

All of the so called prophets of the Lord were absolutely certain what they were proclaiming before the kings was so, but we know that they were under the influence of a lying spirit. What they were proclaiming was absolutely false. Their arrogance is seen when one of them smote Micaiah for disagreeing with him. The moral is someone who seems to have great spiritual discernment can be completely confident, absolutely wrong and totally blind to it. Pride allows people to seek God on their own terms, accept false information as truth and be greatly deceived in the whole process. True spiritual discernment comes at the cost of living in the light and having intimate fellowship with God which demands complete humility.
