Philippians 2: 3-5
3 Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, 4 not looking to your own interests but each of you to the interests of the others. 5 In your relationships with one another, have the same mindset as Christ Jesus.
People who are not believers often look at the behavior of confessing Christians. As we are on our journey of faith, we must strive to live a life that demonstrates behavior pleasing to God.
Paul encouraged believers in Philippi to imitate Christ in humility in the way they treat one another. It is not necessary to boast about being a disciple for Christ, but it should be demonstrated in the life you live.
By this everyone will know that you are my disciples, if you love one another (John 13:35 NIV).
As Christians, we must daily examine ourselves to see if we are imitating Christ.
