No passage of scripture better fuels my understanding of what it means for the Gospel to be lived out in the Christian life than Paul's words in his letter to the Philippians:
Do nothing from rivalry or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but made himself nothing, taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
It's found in chapter 2 if you want to read it in context.
WOW...In yet another place he calls us throught the cross, not around it!
