Walking in His Righteousness
A Day in the Life
“For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.” — 2 Corinthians 5:21
There are moments in Scripture that do not simply inform us—they arrest us. This is one of them. I find myself slowing down every time I read this verse, almost as if my spirit recognizes that I am standing on holy ground. Paul’s language is deliberate and unsettling. Christ, who “knew no sin”—the Greek hamartia (ἁμαρτία), meaning both sin itself and its consequences—was made to be sin for us. Not merely a bearer of sin, but identified with it so completely that the weight of humanity’s rebellion was placed upon Him. This is not an idea to rush past. It is an exchange that should cause us to tremble and to worship.
As I walk with Jesus through the Gospels, I begin to see this exchange foreshadowed in the way He lived. He consistently moved toward those who were considered unclean, unworthy, and forgotten. He touched lepers, dined with sinners, and restored the broken. Yet what we see in His earthly ministry finds its fullest expression at the cross. Isaiah had already declared, “All our righteousnesses are like filthy rags” (Isaiah 64:6), using language that speaks of something defiled and unfit for God’s presence. Even the best efforts of humanity fall short. I think of Joshua the high priest in Zechariah 3, standing before God in soiled garments, unable to cleanse himself. And yet, God commands, “Take away the filthy garments from him… I will clothe you with rich robes.” That is the exchange—our failure for His righteousness.
This becomes intensely personal when I consider that Jesus did not simply die for sin in general; He bore my sin. Theologian Martin Luther once described this as the “great exchange,” where Christ takes what is ours and gives us what is His. Similarly, John Stott wrote, “The concept of substitution may be said… to lie at the heart of both sin and salvation.” That means when Christ stood under the weight of divine judgment, He was standing in my place. The pain He endured was not only physical but relational—the experience of bearing the Father’s wrath against sin. That reality reshapes how I view forgiveness. It is not casual. It is costly beyond comprehension.
And yet, here is where the message turns from sorrow to transformation. Paul does not end with what Christ took; he points us to what we receive: “that we might become the righteousness of God in Him.” This is not merely a legal declaration—it is a new identity. The same love that we see demonstrated at the cross becomes the foundation for the fruit of the Spirit in Galatians 5. Love—agapē—is no longer something I strive to generate; it is something that flows from who I have become in Christ. Easter is the evidence that this exchange was accepted. The resurrection is God’s declaration that righteousness has been secured and new life has begun.
So as I move through my day, I am not trying to earn God’s approval. I am learning to live from it. That changes everything. When I am tempted to prove myself, I remember that Christ has already done what I could not. When I fall short, I return to the truth that I am clothed in His righteousness. And when I encounter others, I am called to reflect the same love that was extended to me. This is what it means to walk in a manner worthy of what we have received—not in perfection, but in gratitude and transformation.
