Paul advised the Philippians to have the mind "which is yours in Christ Jesus". This refers to Jesus

In Philippians, Paul encourages the believers to have the same attitude as Christ Jesus. This refers to the attitude of humility, selflessness, and obedience that Jesus demonstrated during his life and especially during his death on the cross. Jesus is presented as the ultimate example of humility, who even though he was divine, did not consider equality with God as something to be grasped, but instead emptied himself and became a servant to all. Therefore, to have the mind of Christ is to adopt the same humble and selfless attitude towards others.
