...a house not made with hands (2 Corinthians 5:1)
A God-built home that no human hands have built
It’s who lives there and the love that turns a house into a home.
For we walk by faith, not by sight. (2 Corinthians 5:7)
To walk in the spiritual realm you don’t need physical senses but walk by relying on the word. That’s the walk of faith.
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. (2 Corinthians 5:17)
Our lives are no longer worldly; they are now spiritual. Our “death” is that of the old sin nature which was nailed to the cross with Christ. It was buried with Him, and just as He was raised up by the Father, so are we raised up to “walk in the newness of life” (Romans 6:4). That new person who was raised up is referred to as the "new creation" by Paul in 2 Corinthians 5:17.
For He (God) 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)
Charles Spurgeon called this verse the heart of the gospel. It is the gospel in one verse.
For He (God) made Him (Jesus) who knew no sin
How do we know Christ was sinless? Primarily based on the testimonies of his opponents. When Pontius Pilate, the Roman ruler, investigated Him, he proclaimed, "I see no fault in Him" (John 19:4). When Herod and the Jewish leaders tried Him, they couldn't locate any witnesses against Him, so they gathered a group of false witnesses who lied under oath (Matthew 26:59-60). When Christ was crucified, a Roman centurion said, "Truly this was the Son of God!" (Matthew 27:54).
...to be sin for us
He so identified with sinners that he was counted among the transgressors (Isaiah 53:12). He not only died between two sinners, he was counted among them and died the same way they did–a criminal's death on the Cross.
…..that we might become the righteousness of God in Him.
In this final phrase we have the Great Exchange:
He was condemned that we might be justified.
He bore our sin that we might be set free.
He died so that we might live.
He suffered that we might be redeemed.
He was made sin, that we might be made righteous.
Theologians call it the doctrine of imputation. It means that when we trust Christ our sin is credited to Christ’s account and his righteousness is credited to our account. He takes our debt and we get his credit.
