The desperate disease of the sin-infected human heart requires radical surgery. What sinners need, in fact, is a transplant. A new heart is the only solution. The Apostle Peter begins his first letter with a glorious picture of the way in which God has met sinful humanity in its most fundamental need: “Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead” (1 Peter 1:3). Peter packs an enormous amount of theology and doxology into this verse.
