Identity, what defines it? Is it simply what you do? Is it your occupation? What makes you, you? Many a lost soul has traveled the land trying to "find themselves." In the end one may find new appreciation for living, for creation or for another occupation. Is this what makes up who they are?
Identity is the essence of all that is you. Truly the only way to realize your full potential and be all you are is found in Christ. When we receive the Lord, by virtue of the finished work, we have union with Christ. We abide in Him.
Identity is not what you do or what you abstain from. Identity is who you are. In Christ, because of the finished work, you are complete. This is why it is essential to understand the finished work is in fact finished.
What part of finished is unfinished?
In many Charismatic/Word of Faith circles performance and hard work is still much in order. Granted, they teach a freely received salvation, works free. However, if you want to receive the return on your giving, or healing, then you must work hard and perform well enough to receive it. This is why New Covenant grace is so vital to understand. It is a finished work. We can rest in Him. It is not by achievement we receive from Him it is by identity, by our union with Him.
