What does Romans 8:3 say about the law and sin?

In Romans 8:3, Paul states, 'For what the law could not do, in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh.' This verse highlights the inability of the law to justify the sinner or provide liberation from sin due to the weakness of human flesh. The law reveals sin but cannot empower the believer to overcome it.

God's solution was to send His Son, Jesus Christ, in the likeness of human flesh to address the issue of sin by condemning it through His death. This underscores the core of the Gospel—Christ's substitutionary atonement. By condemning sin in His flesh, Jesus satisfied divine justice, granting believers freedom from the law's condemnation and the power to live righteously by the Spirit.
