Everyone proud in heart is an abomination to the Lord; though they join forces,[a] none will go unpunished.
One of the things that God hates is pride. In many places in the Bible is this clearly stated, being Proverbs 16:5 one of them. But there have always been proud people at all times and in all places. These people believe they are superior to others for different reasons. It could be because they have money or a high social position, or a good education, or being of the majority or dominant race. No matter what motivates pride, God is never pleased that position.
While it is true that, in general, most of the proud people may have the aforementioned characteristics, there can be pride in other social strata. I have met very poor people who are very proud and wealthy people with a humble heart. I have also met proud people of all races and nationalities, as well as humble people of the same origin. Therefore, pride lacks a specific stereotype and can be found anywhere.
Meditate on what the Scripture says in Ezekiel 28:14-17: You were the anointed cherub who covers; I established you; you were on the holy mountain of God; you walked back and forth in the midst of fiery stones. You were perfect in your ways from the day you were created, till iniquity was found in you. By the abundance of your trading you became filled with violence within, and you sinned; therefore I cast you as a profane thing out of the mountain of God; and I destroyed you, O covering cherub, from the midst of the fiery stones. Your heart was lifted up because of your beauty; you corrupted your wisdom for the sake of your splendor; I cast you to the ground, I laid you before kings, that they might gaze at you.
That big, anointed cherub that mentions the prophet Ezekiel is none other than who we know today as the devil or Satan. Scripture says he was perfect from the day he was created until iniquity was found on him. So verse 17 says: Your heart was lifted up because of your beauty; you corrupted your wisdom for the sake of your splendor. The great sin of this cherub was pride. He believed much larger and important than it really was.
Isaiah 14:12-14 sheds more light on the sin of the devil when he was still one of the angels in heaven: How you are fallen from heaven, o Lucifer, son of the morning! How you are cut down to the ground, you who weakened the nations! For you have said in your heart: ‘I will ascend into heaven, I will exalt my throne above the stars of God; I will also sit on the mount of the congregation on the farthest sides of the north; I will ascend above the heights of the clouds, I will be like the Most High.
The pride of Satan was so great prompting him to believe the same God and able to take the throne of the Most High. And if God hates lying because it reminds the father of lies, obviously He must also hate pride because it was the first sin committed in the universe. That pride that even challenged the authority of God and sought to take his holy throne can never be to His liking.
We take away our heart every trace of pride. Let as Psalm 51:17 says: The sacrifices of God are a broken spirit, a broken and a contrite heart— These, O God, You will not despise. The best example of humility has made Him our Lord Jesus who humbled himself and gave His life on the cross for you and me. God bless you.
