What does it mean that Jesus was made sin for us?

To say that Jesus was made sin for us signifies that He bore the full weight of our transgressions and faced the punishment that we rightfully deserve. As described in Mark 15 and parallel passages like 2 Corinthians 5, Christ was without sin, yet He was identified with our sinful state on the cross. This wasn't merely a symbolic act; it was a divine exchange where the sinless Son of God took our place, becoming a curse in our stead. His righteousness is then imputed to us, offering a complete erasure of guilt and restoration to right standing with the Father. This profound doctrine is central to understanding both our need for salvation and the grace that is afforded to us through faith.
