How do we know that pride is a problem for Christians?

In the passage from Luke 22, we see the disciples engaging in a dispute about who is the greatest among them, even during such a significant moment with Jesus. This incident illustrates the deep-rooted pride and ambition that can linger in human hearts, often overlooked or minimized. Despite the close relationship the disciples had with Christ, they still struggled with self-esteem and a desire for preeminence, showcasing the continuous battle against pride even among believers. The Scripture encourages Christians to remain vigilant against such tendencies, promoting instead a mindset of lowliness and valuing others above themselves, as seen in Philippians 2:3.
