The Greatest Event in human history was the death, burial, and resurrection of Jesus Christ. The Greatest Exchange was His life for ours. 2 Corinthians 5:21 "For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him." Romans 5:8 "But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us."
