"That Birth, Not Performance, Determines Identity"
Your identity in Christ is solid and secure, not because of what you do or don't do, but because you've been reborn as a new creation!
From the book:
A toad is not a toad because it croaks and eats bugs. I wouldn't recommend it, but you could eat bugs till you croaked, and it wouldn't turn you into a toad. A toad is a toad because it was born a toad.The point here is that we inherited our sinful identity from Adam, just by being born. And now we've inherited a brand new identity - righteous, holy, alive to God - just by being spiritually reborn! Your identity is by your birth, not by your behavior or performance.
You're a human by birth. Your mom didn't pause between labor pains and pray, "Oh, God, please let it be a human!" Birth determined your human identity. This holds true in the spiritual realm as well. As a spiritual product of Adam, you are a sinner by birth (Romans 5:19a). Your performance has nothing whatever to do with your acquiring this identity...
...When witnessing to lost folks, I used to tell them that if they could live a perfect life they would go to heaven, but since they've already blown that one, they need a Savior. Although a person can come under conviction and get saved via this method, my theology was wrong. Even if it were possible for man to keep God's Law perfectly, he would still go to hell because of the spiritual identity he acquired at birth.
