Let this mind be in you which was also in Christ Jesus, Who being in the form of God did not consider it robbery to be equal with God but made himself of no reputation, taking the form of a servant and coming in the likeness of men. Being found in appearance as a man, he humbled Himself and became obedient to death, even the death of a cross.
We can say much about being like Jesus in terms of walking in power, our kingdom authority, and the glory of God but all of that starts with a posture of humility, obedience and total dependence on God which flows out of a relationship of intimacy and trust. True humility can only exhist where personal revelation of our worth and value to God exhists first. Without this there is no lowering of ourselves to begin with.
We must recognize and understand that we exist for God, period. He created us for His pleasure and glory (Revelation 4:11). When that becomes our desire, His pleasure and glory becomes what motivates us, and the rest is easy. All of our worth and value must come from abiding in Christ and communion with the Father. It is the reason Jesus said, "apart from Me you can do nothing ."
I am called to live in perfect relation to God (it was his original intent when he created us to begin with) so that my life produces a longing after God in other lives, not admiration for myself. Unfortunately when our identity isn't rooted and grounded in Christ this is often the result.
