New Defender's Study Bible Notes
2:5 this mind. As followers of Christ, we should try to think as He would think, walk as He walked (I John 2:6) and love as He loved (John 13:34). With renewed minds (Romans 12:2), we can and should have “the mind of Christ” (I Corinthians 2:16).
2:6 form of God. Jesus Christ was God from eternity (John 1:1-3), the Creator of all things.
2:6 not robbery. He was not fearful of losing His deity when He exchanged the outward form of God for the outward form of man; that is, He did not have to cling to His deity as a robber would his plunder. He could not cease being God. The word for “robbery” is used only this one time in the New Testament.
