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

The phrase "which is yours in Christ Jesus" refers to humility. Paul urged the Philippians to adopt the same attitude of humility that Jesus had demonstrated by leaving his divine glory to become human and suffer death on the cross. Jesus willingly gave up his status and power to serve others, and Paul encouraged the Philippians to follow his example by considering others as more important than themselves and looking out for the interests of others.
