Today I found some more great writing by Tullian Tchividjian on the subject of Our New And Exalted Identity in Christ:
While the world constantly tempts us to locate our identity in something or someone smaller than Jesus, the gospel liberates us by revealing that our true identity is locked in Christ. Our connection in and with Christ is the truest definition of who we are....If you are not reading his blog on a regular basis, why not? Always some good Gospel stuff there!
...The gospel frees us from this pressure to perform, this slavish demand to “become.” The gospel liberatingly declares that in Christ “we already are.” If you’re a Christian, here’s the good news: Who you really are has nothing to do with you—how much you can accomplish, who you can become, your behavior (good or bad), your strengths, your weaknesses, your sordid past, your family background, your education, your looks, and so on.
Your identity is firmly anchored in Christ’s accomplishment, not yours; his strength, not yours; his performance, not yours; his victory, not yours. Your identity is steadfastly established in his substitutionary life and death, not your sin.
Now you can spend your life giving up your place for others instead of guarding it from others—because your identity is in Christ, not your place.
Now you can spend your life going to the back instead of getting to the front—because your identity is in Christ, not your position.
Now you can spend your life giving, not taking—because your identity is in Christ, not your possessions.
