Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. Let each of you look out not only for his own interests, but also for the interests of others. Let this mind be in you which was also in Christ Jesus.
Listen to the "Verse by Verse" episode covering this scripture.
The goal of Christian conversion and transformation is to become like Jesus Christ—to think like Him, to love others as He does, to have His mind in us.
Paul lists some of the changes that are necessary for a natural, selfish human mind to become like Jesus Christ’s mind. We must remove selfish ambitions and “empty pride,” replacing them with “lowliness of mind.”
“The Greek word suggests a deep sense of humility. Although the pagan writers used the word negatively, in effect to mean abjectness or groveling, Paul did not. What Paul was calling for was an honest evaluation of one’s own nature. Such an evaluation should always lead to glorification of Christ” (NKJV Study Bible, comment on Philippians 2:3).
Elsewhere Paul says it is not wise to compare ourselves with others (2 Corinthians 10:12). But when we do assess ourselves and do consider others, we should “be severe upon our own faults and charitable in our judgment of others” (Matthew Henry’s Commentary, comment on Philippians 2:1-11).
