Why is self-pity a danger for Christians?

As exemplified in the life of Elijah, self-pity can consume a believer, causing them to focus inwardly rather than on fulfilling God's mission. Elijah's lamentations reveal how self-focus can lead to despair and idleness—he bemoaned not being appreciated while neglecting the divine calling on his life. Christians should recognize this tendency and combat it with the understanding that our identities and success are rooted in God's grace and not in visible accomplishments or accolades from others. Our effectiveness depends on God's power, not our perceived successes.
