Jesus is the illustration of this. Let this mind be in you which was also in Christ Jesus. The frame of mind. What was His attitude when he came? He did not come to get ministered to but to minister to others. Jesus took on the form of the servant, a slave. He submitted Himself voluntarily to the death of the cross in order to satisfy the punishment and penalty for our sins. That is called taking the low road. He became poor that we might become rich, not materially, but spiritually.
It is the perfect example of Deny yourself, take your up your cross daily, and follow God the Father. That was His motive and philosophy when He came. Jesus Christ had the attitude and the frame of mind that we are to have. And how can we have that? Because we have the Spirit of Christ living inside of us. These are things that that God's Spirit through God's word forms in us.
