Proverbs 21:4

Haughty and arrogant eyes and a proud heart, the lamp of the wicked (their self-centered pride), is sin (in the eyes of God).

Seven things lead to pride: fear, entitlement, ingratitude, people-pleasing, not praying, hypocrisy, and rebellion. They all focus on the self and not focus on God. Pride is a trust issue and self-protective, elevating personal wisdom over the wisdom of God.
