I saw a post on Twitter to the effect: The only way to receive all that Jesus has for you is to be all that He wants you to be.
It sparked a thought: The only way you can be all that He wants you to be, all that you can be or would like to be, is to receive all that He is. Jack Taylor, in his book The Key to Triumphant Living, shared a prayer. As I recall he said, "Lord, do whatever you need to in me and to me in order to do whatever you want to through me."
In order to be perfect as He is perfect, in order to be all that He wants us to be, we must first be yielded to Him - or as He put it, "deny yourself, take up your cross, and follow Me." It is as we let go, and allow Him to be our life, that we are able to live the life He desires for us. "The word [logos, message] of the cross [i.e., death, death to self, and the victory that comes with it, and the various implications of it for our Christian life and daily living] is foolishness to those who are perishing, but to us who are being saved, it is the power [dunamis, inherent capability] of God."
Be all that you can be. It isn't through great training, pride in yourself, or esprit de corps. It isn't through the inherent ability of the human being.
Be all that you can be. It comes through ceasing from your own labor and resting in the finished work of Christ. That is the Sabbath that remains to the people of God. (Heb.4:9-11). That's the Christian Sabbath. It isn't a day of the week. It's a lifestyle of faith - resting in the sufficiency of the Lord to accomplish His will - both to will and to work for His good pleasure (Philippians 2:13), and to complete that which He has begun in you (Phil. 1:6).
