As far as the Law is concerned I may consider that I died on the cross with Christ. And my present life is not that of the old “I,” but the living Christ within me. The bodily life I now live, I live believing in the Son of God, who loved me and sacrificed himself for me. (Galatians 2:19,20)
Good gracious! Now this is the glory our lives are meant to be!
Take those last three sentences in steps:
1) You and I are dead to the Law; there is no damnable, damning evidence of sin even available to condemn us anymore. Jesus “did not come to abolish the Law, but to fulfill it,” and, in fulfilling it, He put to death its demands upon us.
2) The “old I” is gone now. The sinful, self-aware, self-obsessed old Self lives no longer – and what has replaced it?
3) “The living Christ within me.” What?! The God of the universe, the Creator and Sustainer of all things, the Savior of the world has chosen to take up residence…in me?! yes! He’s alive and He’s living in me! And in you too, my friend! Oh, that you and I would learn to submit our minds and spirits and personalities to allowing Him to supersede our minds and spirits and personalities! He knows how to walk out His Way – He’s already done it once! – oh, won’t we let Him do it all over again in us?
So what’s left for us to do?
4) To simply “live believing in the Son of God, who loved me and sacrificed himself for me.” This is the essence of what Jesus meant when he answered the crowd in John 6: “This is the work of God, that you believe in Him whom He has sent.”
So, to sum up thoughts 1-4 in one contiguous sentence, here we go: To Believe in Jesus is to walk in a Union-with-Him that creates the “new I,” causing us to be dead to the Law and sin! Thank you, Jesus, that it's all your work!
