Pride is a big I and leads to a downfall from grace.

Now all the people of Judah took Uzziah, who was sixteen years old, and made him king instead of his father Amaziah. Uzziah was sixteen years old when he became king, and he reigned fifty-two years in Jerusalem. His mother’s name was Jecholiah of Jerusalem. God helped him against the Philistines, against the Arabians who lived in Gur Baal, and against the Meunites. And he made devices in Jerusalem, invented by skillful men, to be on the towers and the corners, to shoot arrows and large stones. So his fame spread far and wide, for he was marvelously helped till he became strong. But when he was strong his heart was lifted up, to his destruction, for he transgressed against the Lord his God by entering the temple of the Lord to burn incense on the altar of incense. So Azariah the priest went in after him, and with him were eighty priests of the Lord —valiant men. And they withstood King Uzziah, and said to him, “ It  is not for you, Uzziah, to burn incense to the Lord, but for the priests, the sons of Aaron, who are consecrated to burn incense. Get out of the sanctuary, for you have trespassed! You shall have no honor from the Lord God.” Then Uzziah became furious; and he had a censer in his hand to burn incense. And while he was angry with the priests, leprosy broke out on his forehead, before the priests in the house of the Lord, beside the incense altar. And Azariah the chief priest and all the priests looked at him, and there, on his forehead, he was leprous; so they thrust him out of that place. Indeed he also hurried to get out, because the Lord had struck him. King Uzziah was a leper until the day of his death. He dwelt in an isolated house, because he was a leper; for he was cut off from the house of the Lord. Then Jotham his son was over the king’s house, judging the people of the land. 2 Chronicles 26:1,3,7,15-21 - NKJV
