“…who His [Jesus] own self bare our sins in His own body on the tree, that we being dead to sins, should live unto righteousness.” – 1 Peter 2:24
Jesus bore in his body our sins. Before we were born, Jesus took upon Himself every sin you would ever commit. 
Bearing every weight of sin in His body, when He died on the cross, our sin died. Romans 4:25 says that Jesus was “…delivered up for our trespasses…”.
Our sin died with Him.
“…that we being dead to sin, should live unto righteousness.”
When we encounter the cross and receive salvation, God raises us up and makes us alive. 
“…even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved— and raised us up with him and seated us with him in the heavenly places in Christ Jesus…” Ephesians 2:5‭-‬6
One of the main points of Pauls’s doctrine was consider yourselves dead to sin and reckon yourselves alive in Christ. In other words, realize that you are no longer a slave to sin. That’s not who you are! It has no power over you. You are no longer slaves, but friends of God. 
“For He made Him [Jesus] who knew no sin to be sin for us, that we might become the righteousness of God in Him.” 2 Corinthians 5:21
Jesus bore the cross for our sin, but He was “…raised for our justification.” (Romans 4:25).
We are now the righteousness of God in Christ Jesus. It means right standing with God, but it means so much more! It means we get to live without a sense of guilt, shame, and condemnation.
This righteousness has nothing to do with us. We didn’t do enough good to earn it. It’s not dependent upon our weaknesses or strengths. It was given to us. It was imputed to us. He took our sins so that we could take upon ourselves His righteousness.
“Behold, the Lamb of God who takes away the sins of the world.” John 1:29
He takes it away. All of it. Every sin paid in full by the cross – His blood. That sin, that addiction, the bondage – on the cross, He declared it finished when He said: “It is finished!”.
A life of victory hinges upon who you believe God is and who you believe you are.
Jesus “who His own self bare our sins in His own body on the tree, that we being dead to sins, should live unto righteousness”.
Your identity is His righteousness. Not your sin. Regardless of what yesterday or this year has looked liked, choose today to walk in who Jesus has already declared you to be since you came to Him in salvation: Righteous. Free. Friends of God.
