“Let this mind be in you, which was also in Christ Jesus: who, being in the form of God, thought it not robbery to be equal with God: but made Himself of no reputation, and took upon Him the form of a servant, and was made in the likeness of men: and being found in fashion as a man, He humbled Himself, and became obedient unto death, even the death of the cross. Wherefore God also hath highly exalted Him, and given Him a name which is above every name: that at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.” Philippians 2:5-11 (KJV)
The mind of the Christian is not empty of thought. According to Paul the apostle to the Corinthians “…We have the mind of Christ” (1 Corinthians 2:16). So having the mind of Christ we will think like Jesus thinks, act like Jesus acts; because that is His mind.
The mind of Christ was to submit Himself to the Father’s will, and glorify His name. That is the mind of the Christian too. Even unto death.
