At the root of egotism is self. Egotism is ultimately driven by and thinking oneself worthy of the utmost attention or capable of complete self-sufficiency. At times, an egoist may be motivated by past hurt. Betrayal, abuse, or abandonment may cause a person to believe he must always look out for himself—because no one else will. Rather than trust others, someone who has been hurt may isolate herself and believe she can only trust herself. Though not pride as we would generally conceive of it, this is still an unbiblical stance that raises self to the status of a god.
is one passage that speaks to egotism. Verses 3–4 say, “Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others.” We are to look to the interests of others based on the example of Jesus Christ, who, though He is God, humbled Himself to live a human life and die a humiliating death in our stead. In both the Old and New Testaments, followers of God are called to humility; we are not to have an over-inflated sense of self-importance. Humility is not self-debasement or a lack of confidence. Being humble does not mean that we neglect our own needs or uphold no . Rather, humility is having an accurate estimation of oneself wherein we think of ourselves less often. We are not preoccupied with ourselves; rather, we see and care about the needs of others. We are willing to sacrifice our own preferences for the benefit of others.
Christians understand that serving self is not the highest goal." GotQuestions.org
