What does the Bible say about sin and pride?

The Scripture reveals that pride is a significant aspect of our sinful nature, as demonstrated in the life of Hezekiah. Despite being a faithful king, Hezekiah succumbed to pride when he showed the treasures of his house to the Babylonian ambassadors without giving glory to God. This pride led to God's chastening, illustrating that even the most sanctified believers can fall into sin without God's sustaining grace. As outlined in Romans 7, the struggle with sin and pride is a universal experience for believers, emphasizing the need for reliance on God's grace to combat these inclinations.
