Why is it unbelievable that we become the righteousness of God?

The notion that believers are made the righteousness of God in Christ is indeed a staggering truth that challenges human understanding. As stated in 2 Corinthians 5:21, for our sake, God made Christ to be sin, so that in Him we might become the righteousness of God. This reality transcends our natural perceptions and reflects the depth of God's grace. It illustrates that, through faith in Christ, our sinful record is exchanged for Christ's perfect obedience and righteousness. This truth emphasizes that our standing is not based on our works but solely on Christ's atoning sacrifice, which is why it is labeled as unbelievable – it defies human logic and speaks to the miraculous nature of salvation.
