“But once [Uzziah] became powerful, his pride destroyed him. He disobeyed the Lord his God. He entered the Lord’s temple to offer incense on the incense altar.”
2 Chronicles 26.16
The sequence is well known in Scripture and in life: power, pride, and disobedience. God struck Uzziah with leprosy, and he died excluded from the Lord’s presence and from the people.
Most anything can become a point of pride for us, but pride inevitably leads to downfall. God exalts the humble; he does not tolerate the proud.
