God’s Mercy and God’s Wrath Meet at the Cross 

The cross of Jesus Christ is all about God’s holiness. That may seem strange, that a place of blood and suffering and torment would be all about holiness. But the cross answers this question: How can a holy God be reconciled to unholy people? That question demands this one: How can the relationship between a holy God and an unholy people be restored without some gross act of injustice?
