He died to pay the penalty for your sins.
I passed on to you what was most important and what had also been passed on to me. Christ died for our sins, just as the Scriptures said. He was buried, and he was raised from the dead on the third day, just as the Scriptures said (1 Corinthians 15:3-4).
Christ suffered for our sins once for all time. He never sinned, but he died for sinners to bring you safely home to God. He suffered physical death, but he was raised to life in the Spirit (1 Peter 3:18).
