2 Chronicles 26:15-16–In Jerusalem he made engines, invented by skillful men, to be on the towers and the corners, to shoot arrows and great stones. And his fame spread far, for he was marvelously helped, till he was strong. 16 But when he was strong, he grew proud, to his destruction… 
One of the more humbling things you can experience is to support, sacrifice, or help someone get to a stable place in life, and they forget it.  The pride to want to take credit or adorn ourselves with our accomplishments, without paying homage to those who helped get us there, is one way we show our ingratitude as sinners…(Luke 17:15-18, 1 Corinthians 4:8-16)
The passage above refers to a great King in Judah’s history, King Uzziah.  A young sixteen-year old king, who grew to have a great mind in advancing Judah in it’s technology of waterways and agriculture.  God favored him in war, and enabled him to gain fame among the surrounding nations, giving him “great help” until he was made strong.  But his strength eventually turned into prideful destruction…
When you think about this narrative, it sounds like a teenager who has had parent(s) who well equipped them for independence, but use that same instilled confidence for independence to turn against the parents.  They have been “marvelously helped”, yet pride has a way of forgetting our “help”, and realizing that such confidence didn’t originate from us alone…
Many say it’s a product of youth, but really it is a product of immaturity.  Because I have seen people have strong gratitude as young teenagers for their parents, and those who are middle aged with older parents and ungrateful!  This doesn’t excuse neglectful parents, because in this context God was everything but neglectful towards King Uzziah.  But the King was ungrateful towards all God gave him, which pride causes us to forget…(James 1:17)
Pride in it’s essence is blinding.  Because pride conveniently “forgets” it was helped, which is why we boast in ourselves, not God or anyone who has helped us.  What angers God when we dismiss Him, is that our desire for credit or to “win”, is more powerful than our thanksgiving and praise to Him as root the cause!  That is why a focus on Christ and the cross, helps remind us of what it cost for every good and perfect gift in our life, that we not live blind like Uzziah did…
